He received permission from the authors to post the undated code. <p>I’d take it that the code is in 6502 assembly and the program works the whole Apple II memory map for functionality. Did ITS have a 6502 cross-compiler or did the MIDAS program have separate target environments? <p>Very interesting programming archaeology – <a href="https://github.com/PDP-10/its/blob/master/src/aplogo/logo.958">see the source code yourself</a> along with the <a href="https://github.com/PDP-10/its">full PDP-10 ITS image</a> still maintained today. <hr><em> Source: </em><a title="https://blog.adafruit.com/2018/10/04/the-apple-ii-source-code-for-the-logo-language-found/" href="https://blog.adafruit.com/2018/10/04/the-apple-ii-source-code-for-the-logo-language-found/"><em>https://blog.adafruit.com/2018/10/04/the-apple-ii-source-code-for-the-logo-language-found/</em></a>pldworldhttp://www.blogger.com/profile/17285966456574469542noreply@blogger.com0tag:blogger.com,1999:blog-13503312.post-87447027208900032422018-05-14T10:21:00.000+09:002018-05-14T10:21:50.797+09:00Free DNS Lists...<span style="font-family: "Courier New", Courier, monospace;"><span style="font-size: small;">** 2018-05-14 **</span></span><br />

That included adopting the Intel 8088 microprocessor as the heart of the computer. <p>This “outsourcing” attitude extended to the software as well. Although IBM had prodigious internal software development resources, for the new PC they supported only operating systems that they did not themselves write, like CP/M-86 from Digital Research in Pacific Grove CA, and the Pascal-based P-System from the University of California in San Diego. But their favored OS was the newly-written PC DOS, commissioned by IBM from the five-year-old Seattle-based software company Microsoft. <p>When Microsoft signed the contract with IBM in November 1980, they had no such operating system. They too outsourced it, by first licensing then purchasing an operating system from Seattle Computer Products variously called QDOS (Quick and Dirty Operating System”) and 86-DOS. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiSdAkku8aZGzP9UA4ogYVrYMyieowIlirVqUsf6J6nBujCnFaLLm3IUTfzNePT3BbUt2OrXwMVFC-30L6RnAaqtGPbFg9CuQ71PgLLIX-nOzZop3yrT9D1JFADFaCktV4neUY/s1600-h/IMG_19771-284x300%25255B2%25255D.jpg"><img title="IMG_19771-284x300" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="IMG_19771-284x300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEV1EpIchbrX-zFgaQD5PZwlBSLaNm0d3u9S3XEaKty-VaieZQcFDDZOiVD3ACtI8PMCQ0u60hJcnCC_KL4PVNBCyHFXdKaYKzF57wi3h9e9B3QZukZh1X5IzVwMgAg5cJwhA/?imgmax=800" width="231" height="244"></a> <p>PC DOS version 1.0, which supported only floppy disks, was shipped when IBM first released their PC in August 1981.

IBM visited Digital Research in August 1980 – some say at the suggestion of Bill Gates – to investigate using “CP/M-86″, their upcoming version for the 16-bit Intel 8088/8086 processor, on the IBM PC then under development. But they were not able to agree on licensing terms, so IBM left and pursued other options. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhl2xsxeHFTmMUH-vcdPdQ8t_mSWnvYT8rlYofvnGpfOdZx4QGzSzvvqZHxDkdj_uVzKFRqEPsMihzMDbi3F9iw7hWdKZx6wTodSlBmECn8s5prm19m1KTkHON4PZa3Jim1ZP8/s1600-h/TimPaterson1986-542x748%25255B2%25255D.jpg"><img title="TimPaterson1986-542x748" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="TimPaterson1986-542x748" src="https://lh3.googleusercontent.com/-mLEHI_vfFds/V3I3yLi1ZVI/AAAAAAAAArQ/SR1enhDlvY0/TimPaterson1986-542x748_thumb.jpg?imgmax=800" width="178" height="244"></a><br>Tim Paterson in 1986 <p>IBM had already contracted with Microsoft to provide a BASIC interpreter for the PC, so they asked them to investigate also providing the operating system. Microsoft proposed licensing “86-DOS”, which had been written by Tim Paterson at Seattle Computer Products (SCP) for their 8086-based computer kit because the 16-bit version of CP/M was late. <p>When SCP signed the licensing deal <a href="http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/#footnote-7">[7]</a> with Microsoft, they didn’t know for sure who the computer manufacturer was. Paterson said “We all had our suspicions that it was IBM that Microsoft was dealing with, but we didn’t know for sure.” <a href="http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/#footnote-1">[1]</a> He left SCP to work for Microsoft in 1981. “The first day on the job I walk through the door and ‘Hey! It’s IBM.’” <p>Microsoft originally licensed 86-DOS in December 1980 for a flat fee of $25,000. By the next summer they recognized the importance of owning it and being able to license it to other companies making IBM-PC clones, so they purchased all rights for an additional $50,000. <p>Over the next 11 months Paterson worked for Microsoft, interacting intensely with the IBM engineers developing the PC in Boca Raton, Florida. Version 1.0 of PC-DOS was complete in July 1981, one month before the announcement of the IBM PC. <p>SCP later sued Microsoft, claiming that they had concealed its relationship with IBM in order to purchase the operating system cheaply. SCP ultimately settled out of court for almost $1M. <h4> </h4> <h4>MS-DOS ≠CP/M</h4> <p>There were many similarities between CP/M and MS-DOS. Inspired by the 8-bit CP/M, Paterson’s 16-bit operating system used similar commands and some of the same programming interfaces, but it was a different internal implementation and used different file storage formats. <p>At Digital Research, Gary Kildall’s opinion was that MS-DOS infringed on their copyrights for CP/M. He was furious, and confronted both Bill Gates at Microsoft and IBM, but his lawyer recommended against a lawsuit. ”Rather than sue, Kildall agreed to license CP/M to Big Blue. But he was astounded that when the PC was released, IBM charged $240 per copy for CP/M, and only $40 for DOS.” <a href="http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/#footnote-3">[3]</a> Needless to say, the Microsoft offering became the dominant operating system for the IBM PC. <p>Paterson denied any wrongdoing. “I told him [Kildall] I didn’t copy anything. I just took his printed documentation and did something that did the same thing.” <a href="http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/#footnote-5">[5]</a> <p>Thirty years later, Bob Zeidman, a programmer and expert in software intellectual property cases, conducted a detailed forensic examination of the code of QDOS, CP/M and PC-DOS. His conclusion? “QDOS was absolutely not copied from CP/M, and MS-DOS showed no signs of copying either. Kildall’s accusations about Bill Gates were totally groundless.” <a href="http://www.computerhistory.org/atchm/microsoft-ms-dos-early-source-code/#footnote-4">[4]</a> <h4> </h4> <h4>From PC-DOS 1.0 to MS-DOS 2.0 and beyond</h4> <p>Version 1.0 of PC-DOS was released with the first IBM PC in August 1981. Version 1.1, which supported double-sided (320 KB) floppy disk drives, was released in May of 1982. <p>In the meantime, a team of Microsoft programmers that included company co-founder Paul Allen was working on a major revision to add hierarchical subdirectories, and to support the hard disks that would be available on the IBM PC-XT. DOS 2.0 was almost twice as big as DOS 1.0, using 28 Kbytes of memory instead of 12 Kbytes. It shipped in March 1983 with the PC-XT as PC-DOS 2.0, and was released to other computer manufacturers as MS-DOS 2.0. <p>MS-DOS continued to be enhanced until the late 1990s, by which time Windows and other advanced operating systems with graphical user interfaces had taken over. <h4> </h4> <h4>What early versions MS-DOS did</h4> <p>An operating system that fits in 12 or 28 Kbytes of memory is very different from the large and complex operating systems we use today. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2MdKea6Vp8krV1Vz2bZsGcbox7iTX4VbDx-QQwSnmOibZowwr2LbylRVFxVt0hQRqZ3yLXQH5f1_nkCsK5dJW7qnh77BtIX_bH7E1wDkcsZScO9tmnuUujFB9lugViIxAyZw/s1600-h/DOS20_screenshot-542x519%25255B2%25255D.jpg"><img title="DOS20_screenshot-542x519" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="DOS20_screenshot-542x519" src="https://lh3.googleusercontent.com/-TlN_xXHiPEM/V3I3zQS3n_I/AAAAAAAAArg/d0iuqBoVi_A/DOS20_screenshot-542x519_thumb.jpg?imgmax=800" width="244" height="234"></a> <p>MS-DOS was basically a file manager and a simple program loader. The user interface was text commands typed on a keyboard, followed by text responses displayed on the screen. There was no graphical output, and no mouse for input. Only one user application program could run at a time. File names were limited to 8 characters, plus a 3-character extension indicating the file type. There were commands like “dir” to list the files in a directory, and “del” to delete a file; you ran a program by typing the name of its executable file. <p>In addition to adding hierarchical directories and hard disk support, the rewritten version 2.0 included many other new features: installable device drivers to support the growing list of available peripheral devices such as printers, background processes (“terminate-and-stay-resident”) that allowed print spooling, redirection that allowed the output of one program to be the input to another, and support for 9-sector floppy disks that increased capacity from 320 KB to 360 KB. <p>Despite its primitive facilities, for fifteen years DOS was the bedrock upon which thousands of application programs running on millions of IBM PCs and PC clones depended. <h4> </h4> <h4>Acknowledgements</h4> <p>I had the source code for version 2.0 on 5″ floppy disks in my attic for 30 years, but we needed Microsoft’s permission to release it. We are very grateful to Roy Levin, Managing Director of Microsoft Research, Silicon Valley, for working many months to make that happen. <p>But I didn’t have the source to the earlier version 1.1, and neither, apparently, did Microsoft.

<p align="justify"><b><font size="2">들어가면서..</font></b></p>
<p align="justify"><font size="2">인텔진영이 시끄럽다. 인텔이 3.06Ghz에서 안정적인 동작을 위해 메인보드
제조사들에게 FMB2에서 70A의 규격을 만족시키는 전원부를 구성하기를 권하면서부터 기존 메인보드들의 전원부 구성에 대한 되새김질이 늘고
있다. 또한 i845PE 메인보드의 전원부 구성에 대한 의구심이 들기 시작하면서 이전까지 그냥 넘어갔던 전원부 구성을 다시한번 돌이켜보게
하고 있다.</font></p>
<p align="justify"><font size="2">또한 이때부터 많이 언급되기 시작한 단어가 바로 'Phase'라는 단어이다.
사실 처음으로 Phase가 제대로 언급되기 시작한것은 Pentium 4 3.06Ghz문제부터가 아니라 Iwill의 XP333 부터라고
해도 과언이 아니다. Iwill XP333은 특이한 구성과 설계로 세간의 관심을 가장 많이 받아온 제품으로, 다른건 모르겠으나 '전원부'하나는
가장 안정적인 AMD메인보드로 손을 꼽았고, 이런 관심을 받아온데 가장 큰 이유가 바로 3 Phase Power Solution
구성때문이다.</font></p>
<p align="justify"><font size="2">이후 수면아래로 가라앉다 다시 Pentium 4 3.06Ghz에서 인텔이
70A 규격을 만족시키는 전원부를 공고한 점, 이후 digitimes에서 이를 '인텔은 4 Phase 구성의 전원부를 권장한다'는
뉘앙스의 글을 포스팅하고 나서부터 전원부 구성과 Phase에 대한 많은 관심이 대두되어 왔다. 또한 현재 내가 사용하고 있는 메인보드는
어떤것이며, 앞으로 구입해야될 메인보드가 어떤 Phase 구성인지가 상당히 대두되고 있는 시점이다.</font></p>
<p align="justify"><font size="2">또하나의 이슈가 있다. i845PE메인보드 대부분이 PCI Clock
FIX기능을 지원하면서부터, 오버클럭률에 많은 관심을 보였으며, 'Phase'가 높을 수록 오버클럭이 잘된다는 설이 유포되기 시작하면서
'당연히' Phase 에 대한 관심이 높아졌다. 따라서 우리는 메인보드의 전원부 구성에 대하여 깊이있게 살펴보고, 어떤 결론을 내려야
할지 관심있게 지켜보고자 한다.</font></p>
<p align="justify"><font size="2">사실 이 글은, 앞으로 포스팅 될 'i845PE메인보드 오버클럭 벤치마크'의
앞부분이었으나, 설명이 길고 복잡하여 별도의 칼럼으로 분리하여 포스팅하기로 결정하였다. 따라서 이 글을 읽는분은 앞으로 포스팅 될
오버클럭 벤치마크 기사를 보시는데 많은 도움이 되리라 확신한다. </font></p>

<br />Processors, memory, manufacturing processes, chip architecture, EDA, MEMS, RF, touch screens, servers and the Internet of Things are markets where startups can still make a difference. <br /><br />What follows are ten rising companies worth tracking in 2013.<br /><br /><br /><b>Nantero Inc.</b> (Woburn, Mass.) was founded in 2001 and has
been working on the use of carbon nanotubes in non-volatile memory
applications since then. Having made some noise about a trench-based
device structure in 2006 things went quiet again until 2012. <br /><br />The
company has changed its device to an even more scalable in-via
structure and has announced additional funding of $10 million led by a
couple of strategic partners. In addition microelectronics research
center IMEC (Leuven, Belgium) announced a joint development program to
make CNT non-volatile memories with critical dimensions of less than
20-nm, and senior IMEC executives expressed the hope that the memory
could be deployed as a replacement for DRAM.<br /><br />If this technology is going to fly it should be able to demonstrate more
progress in 2013 and perhaps we will find out who are the strategic
partners?<br /><br /><b></b><a href="http://www.nantero.com"><b>www.nantero.com</b></a><br /><br /><div style="text-align: center;"><img alt="" src="http://eetimes.com/ContentEETimes/Images/News/NanteroCNTRAMelement415.jpg" /><br /></div><br /><div style="text-align: center;"><i><font class="newssubhead">Cross-section of Nantero's carbon-nanotube variable-resistence memory structure.

<b>SuVolta</b><br />
<br />
<strong>SuVolta Inc.</strong> (Los Gatos, Calif.) was founded as DSM Solutions Inc. in 2005 and originally planned to come to market with a novel form of junction FET. The company went through a reappraisal of its chances and then emerged with CTO Scott Thompson on-board in 2011 touting a fully-depleted planar transistor structure that uses doping to recreate what is done by others with silicon-on-insulator wafers. <br />
<br />
Indeed it appeared that PowerShrink transistors with their deeply depleted channel could provide n alternative to FinFET and FD-SOI manufacturing processes, but none of the leading-edge IDMs or foundries appeared to be biting.<br />
<br />
That was until Ajit Manocha, CEO of Globalfoundries Inc. (Milpitas, Calif.) said his company was evaluating a third manufacturing process option – besides FinFET and FD-SOI. That option he called super-steep retrograde well (SSRW), which is basically another name for what SuVolta has been doing.<br />
<br />
It is not clear whether Globalfoundries is working with SuVolta or independently of them. But either way it helps give SuVolta's technology some credibility and is a good reason to keep an eye on SuVolta in 2013.<br />
<br />
SuVolta's PowerShrink transistor manufacturing process achieves
FD-SOI-like benefits without requiring SOI wafers as the starting point.
It achieves some FinFET benefits with needing to make and protect fins.
But will the leading chip companies reject the technology because of
NIH?<strong><span style="font-family: courier new;"><br />

<b>Tela Innovations</b><br />
<br />
<strong>Tela Innovations Inc.</strong> (Los Gatos, Calif.) was founded in 2005 and started by working with Qualcomm on computational lithography with a view to the extraction of multi mask information for the double patterning era. <br />
<br />
Tela's technology is delivered as physical design representation applied to standard cell logic and embedded SRAM, analog and I/O that can result in area savings and reduced leakage current. The company offers gate-length trade-offs for power, performance and area within its libraries. Tela has also specialized in working with customers' IP development teams to get the technology into production. <br />
<br />
In February 2009 Tela acquired Blaze DFM, which added PowerTrim to its technology as well as a relationship with Taiwan Semiconductor Manufacturing Co. Ltd. which bore fruit in 2010.<br />
<br />
The company has been fairly quiet since then but did say mid-2012 that it is ready with libraries for the 32/28-nm and 22/20-nm process nodes. The company's investors provide reasons to watch the company. They include: Intel Capital, Cadence Design Systems Inc., KT Venture Group LLC (the investment partner of KLA-Tencor Corp.) and Qualcomm Inc. The fact that the company appointed an intellectual property legal counsel in 2012 is another reason to be watchful.<strong><br />

<b>Senseg </b><br />
<br />
<strong>Senseg Oy</strong> (Espoo, Finland), formed in 2006, has developed a touch interface technology that uses electrostatic field to create the illusion of surface texture and even the movement of keys beneath the fingers. The technology has the potential to provide haptic feedback for touch screens and particularly the on-screen keyboards that are part of the use of smartphones and tablet computers.<br />
<br />
The company is backed by Ambient Sound Investments, the investment vehicle of the founders of Skype.<br />
<br />
By modulating this attractive force on the fingers a variety of sensations can be generated, including textured surfaces, edges, vibrations and the technology produces tactile sensations with no mechanical vibration. The company appointed a Paul Costigan as CEO in June 2012 and so he should be showing some results from his stewardship of the company in 2013.<br />

<b>SiTime</b><br />
<strong><br />
SiTime Corp.</strong> (Sunnyvale, Calif.), founded in 2005, is a semiconductor company pioneering the use of MEMS timing products.<br />
<br />
Earlier this year SiTime entered into a strategic partnership with Vectron International Inc. (Hudson, N.H.) and Knowles Electronics (Itasca Ill.), both owned by Dover Corp. of New York. The formation of the partnership included a cash investment in SiTime by Vectron, which is a maker of quartz timing products, and by Knowles, which makes silicon membrane microphones. The size of the investment was not disclosed but when the competition starts investing in you, you are probably doing something right.<br />
<br />
SiTime was also ranked as the fastest growing semiconductor company in North America by Deloitte in November 2012.<br />

<b>Wilocity</b><br />
<br />
<strong>Wilocity Ltd.</strong> (Caesarea, Israel), founded in 2007, develops 60-GHz wireless chip sets for the notebook and peripheral markets that can provide data more than ten times faster than today’s wireless LAN solutions. There are numerous competitors but Wilocity appears to have first-mover advantage and announced a number of design wins and partnerships in 2012.<br />
<br />
Wilocity's WiGig technology was selected to provide multigigabit wireless connectivity in a Dell Ultrabook featured at the launch of the Windows 8 operating system. Wilocity is also partnered with Marvell Technology Group Ltd. to bring forward tri-band Wi-Fi solutions enabled with 802.11ad for the computing, networking and consumer electronics segments.<br />

<b>Cyclos Semiconductor</b><br />
<br />
<strong>Cyclos Semiconductor Inc.</strong> (Berkeley, Calif.) founded in 2006, announced in 2012 that it was Advanced Micro Devices Inc. that had achieved the first commercial implementation of its resonant clock mesh technology.<br />
<br />
It was AMD's Piledriver 64-bit core, which operates at up to and in excess of 4-GHz clock frequency, made using 32-nm bulk CMOS. It was reported to save 24 percent of the power consumption in the clock distribution while achieving previous clock-skew targets.<br />
<br />
That leaves upside for the likes of Intel and ARM's partners if they adopt the technology and we would hope to see announcements in 2013.<br />

<b>Adapteva</b><br />
<br />
Andreas Olofsson, CEO of 2008 startup <strong>Adapteva Inc.</strong> (Lexington, Mass.), has offered innovation in both processor architecture and in funding and business models. To begin with Olofsson managed to make use of multiproject wafer runs to keep costs so low that he was able to boast that he had reached processor IC product release with less than $2 million of total investment, while completing four generations of Adapteva's Epiphany multicore processor. <br />
<br />
Then Olofsson went one better and used the Kickstarter crowd-source funding website to raise more than $750,000 for a project to build a personal supercomputer called Parallella for which building blocks would sell at $99. The computer module is based on a combination of Zynq SoCs from Xilinx and an Epiphany processor from Adapteva. <br />
<br />
The $750,000 is set to fund a mask set but also has the virtue of seeding a developer community of nearly 5,000 potential customers and a lot of awareness. Of course, being innovative is no guarantee of success but we think these innovations merit keeping an eye on Adapteva in 2013.<br />

<b>Neul </b><br />
<br />
<strong>Neul Ltd.</strong> (Cambridge, England) was founded in 2010 to develop a wide-area wireless network technology dedicated to machine-to-machine (M2M) communications and the Internet of Things (IoT). The company has pioneered the development of the Weightless standard for networks that operate in the license-free television white space (TVWS) part of the spectrum. Neul's first product is a radio system specifically designed for TV white space that consists of a base station, battery-powered terminal device, antennas and a set of PC-based network management tools.<br />
<br />
The founders are experienced in nurturing a startup company, many of them having been founders of Cambridge Silicon Radio in 1998 and in 2012 they got a boost from near neighbors ARM, which added its weight to the Weightless Special Interest Group.<br />
<br />
We expect IoT and M2M to be red-hot in 2013 with both Intel and ARM making it an important part of their approach to the market and we also expect Neul to be making news in that sector.<br />

<b>Calxeda</b><br />
<br />
<strong>Calxeda Inc. </strong>(Austin, Texas), a developer of ARM-based processors and software for low-power servers for data centers, has announced in 2012 that it raised an additional $55 million in equity funding. This puts the total raised by Calxeda over $100 million since the company was founded as Smooth-Stone in 2008.<br />
<br />
Calxeda is already shipping the 32-bit EnergyCore processor and with ARM releasing details of 64-bit capable ARMv8 architecture it is expected that Calxeda will continue to make announcements that seek to address a fragmenting server market.<br />
<br />
ARM is a significant investor in Calxeda along with: Austin Ventures, Vulcan Capital, Advanced Technology Investment Co. (the owner of Globalfoundries) Battery Ventures, Flybridge Capital Partners and Highland Capital Partners. So expect to Calxeda to be one of the surrogates through which the ARM versus Intel battle is played out in 2013.<br />

<br />Hi,<br />
We are planning to use TPS23754 in synchronous flyback mode for 1 Gig POE+ application.<br />
In TPS23754EVM-420 ref schematic ,the ethernet interface is not for 1Gig but TPS23754EVM-383 for active clamp forward converter the ethernet interface is for 1Gig.<br />
I want to know if we can use the TPS23754 in synchronous flyback mode for 1 Gig POE+ application.Are there any limitation for TPS23754 in synchronous flyback mode for 1 Gig application.<br />
Please reply<br />
Regards<br />
<br /><i>Posted by <strong>Eric Wright</strong><br />on Nov 12 2012 12:42 PM</i><br />
<br />Any POE, type 2 equipped ethernet transformer can be used with any TPS23754 based PD (and dc/dc converter topology). You can use the J3 jack from TPS23754EVM-383 with the PD on TPS23754EVM-420 for example. Other POE type 2 giga-bit transformer options are Wurth 749022011 or Pulse H6096NL.<br />
<br /><i>Posted by <strong>Arunkumar PB</strong><br />on Nov 14 2012 00:46 AM</i><br />
<br />Hi Eric,<br />
Thanks for the reply .So you mean that we can use TPS23754 in fly back topology for 1Gig application only thing that need to be taken care is the TYpe 2 giga- bit transformer.<br />
<br /><i>Posted by <strong>Eric Wright</strong><br />on Nov 14 2012 08:16 AM</i><br />
<br />Yes, that is correct.<br />

<P align=center><EMBED height=281 type=application/x-shockwave-flash width=500 src=http://www.youtube.com/v/t312usPb9CI?version=3&hl=ko_KR allowfullscreen="true" allowscriptaccess="always"></EMBED></P>
<P align=justify>그러나 표준 USB 3.0의 전력 공급 규격은 900mA까지로, 최대 전력 공급량이 4.5W에 불과해 3.5" 외장 하드디스크 구동은 물론 USB 모니터 구동 등 조금만 소비전력이 높아져도 거추장스러운 전원 어댑터가 필요하며, 최신 태블릿과 스마트폰의 대용량 배터리 충전에 오랜 시간이 걸리는 등, USB의 전력 공급 규격의 개선 필요성이 제기되어왔다.</P>
<P align=justify>이에 따라 USB-IF에서는 지난 7월 USB 케이블을 이용한 최대 100W 전력 공급 규격인 USB Power Delivery 규격을 확정(이하 PD) 발표, 지난 CES 2013에서 이를 이용한 데모를 시연했는데, 이번 기사에서는 USB PD에 대해 자세히 알아보도록 하겠다.</P>
<P align=justify> </P>
<H3 align=justify>USB 2.0 이상에 적용 가능한 USB PD</H3>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd00.jpg" width=500 height=317></P>
<P align=justify>USB PD 규격은 기존 USB 2.0 이상의 규격과 호환을 유지하면서 최대 100W 전력 공급이 가능한 것을 목표로 개발되었기 때문에 기본적으로 USB 3.0은 물론 USB 2.0 이상의 USB 규격에 적용 가능하며, 전력 공급 한계에 따라 총 다섯 가지의 Profile로 구분하고 있다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fusbpd02.jpg" width=500 height=320></P>
<P align=justify>USB PD 규격은 아직 확정되지 않은 Profile0을 비롯해 10W 규격의 Profile1부터 18W 규격의 Profile2, 36W 규격의 Profile3, 60W 규격의 Profile4, 100W 규격의 Profile5로 구분되며, 60W의 Profile4는 마이크로 B/AB 커넥터, 100W의 Profile5 규격은 스탠다드 A/B 커넥터를 사용하도록 규정하고 있다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd15.jpg" width=500 height=243></P>
<P align=center><SPAN style="FONT-SIZE: 10pt">USB PD는 케이블과 장치를 감지해 전력을 자동 조절한다</SPAN></P>
<P align=justify>기존 5V@900mA에 머물던 USB 3.0의 경우 전력 공급 능력이 최대 22배, 5V@500mA였던 USB 2.0의 경우 40배 이상 확대되므로, 안전을 위해 USB PD 규격에서는 케이블의 PD Profile 지원 마커를 포함해 재디자인된 전용 케이블 사용을 권하고 있으며, 케이블 규격을 감지해 공급 가능한 최대 전력을 자동 조절한다.</P>
<P align=justify> </P>
<H3 align=justify>PD 규격을 위해 변경된 커넥터 구조</H3>
<P align=justify>USB PD 규격은 기존 규격과의 호환을 유지하면서 전원 공급 능력을 강화한 규격으로 기존 USB 2.0과 USB 3.0 스펙에서 크게 변한 부분은 없이 기존 USB 커넥터/ 플러그 규격에서 전원 공급과 데이터 교환을 위해 사용되었던 기본적인 핀 구조를 그대로 활용하기 때문에 외형적으로 사용자가 체감할 수 있는 변화는 크지 않다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd04_usb3pd.jpg" width=500 height=179></P>
<P align=center><SPAN style="FONT-SIZE: 10pt">USB 3.0 PD 스탠다드 A 커넥터</SPAN></P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd06_usb3pd.jpg" width=500 height=243></P>
<P align=center><SPAN style="FONT-SIZE: 10pt">USB PD 스탠다드 A 플러그(좌) / USB 스탠다드 A 플러그</SPAN></P>
<P align=justify>USB PD 규격의 커넥터/ 플러그 규격은 기존 USB와 기본적인 규격은 거의 변경된 점이 없지만, 기존 USB 규격과 PD 규격을 구분하기 위해 커넥터에 감지 핀이 추가되고 플러그의 디자인이 소폭 변경되었다.</P>
<P align=justify>즉, PD 스탠다드 A형의 경우 기존 스탠다드 A형과 비교해 PD 케이블 감지와 플러그 삽입 상태를 확인하기 위한 핀이 추가되었으며, 플러그는 커넥터 내부에 PD 감지 핀과의 접촉을 위해 플러그의 금속재 하우징이 약 1mm 가량 길어졌다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd12_connect.jpg" width=500 height=250></P>
<P align=justify>이와 같은 구조 변경을 통해 PD 스탠다드 A 커넥터는 감지 핀을 통해 연결된 해당 플러그(케이블)가 PD 규격을 지원하는지 확인하고, 케이블 내 마커에 기록된 규격에 맞춰 최대 공급 전력을 조절한다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd14.jpg"></P>
<P align=justify>한편, 기존 USB 플러그는 USB PD 커넥터 내의 감지 핀과 접촉하지 않으므로 표준 USB 규격에 따라 전력을 공급(USB 2.0 : 5V@500mA, USB 3.0 : 5V@900mA)하며, 일부 씬 카드의 경우 감지 핀과 접촉되는 플러그 부분을 비전도성 물질로 제조해 잘못된 전력 공급이 이뤄지지 않도록 할 것을 규정하고 있다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd07_udb3pd.jpg" width=500 height=253></P>
<P align=center><SPAN style="FONT-SIZE: 10pt">USB 3.0 PD 스탠다드 B 커넥터(좌)/ USB 3.0 스탠다드 B 커넥터(우)</SPAN></P>
<P align=justify>USB 3.0 PD 스탠다드 B 타입의 경우 기존 Powered-B 커넥터와 동일한 구성으로, 커넥터 중앙 좌측에 플러그 감지를 위한 추가 핀과 플러그 삽입 상태 확인을 위한 핀이 추가되었다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd09_usb2pd.jpg" width=499 height=266></P>
<P align=center><SPAN style="FONT-SIZE: 10pt">USB 2.0 PD 스탠다드 B 커넥터</SPAN></P>
<P align=justify>USB 2.0 PD 스탠다드 B 커넥터의 경우 기본적으로 USB 3.0 PD 스탠다드 B 커넥터에서 USB 3.0을 위해 추가된 부분을 제거한 형태로, PD 규격 케이블 감지를 위한 핀이 중앙 좌측에 추가되었다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd_icon.jpg" width=500 height=129></P>
<P align=justify>커넥터와 플러그가 기존 버전과 호환성을 유지한 채 PD 규격 케이블 감지를 위한 구조가 추가된 만큼 케이블 역시 해당 케이블이 지원하는 PD Profile 감지 기능을 제공하도록 요구하고 있으며, 안전을 위해 처음에는 표준 USB 규격으로 동작해 PD Profile을 감지한 후 해당 PD Profile 규격에 따라 동작하는 방식을 취하고 있다.</P>
<P align=justify>한편, USB PD 규격은 USB 2.0과 USB 3.0을 모두 지원하므로 각각의 아이콘으로 구별하고 있는데, 기본적으로 해당 USB 규격의 표준 아이콘과 배터리를 뜻하는 아이콘을 결합해 구분하고 있다.</P>
<P align=justify> </P>
<H3 align=justify>호환성을 유지하며 발전해가는 USB</H3>
<P align=justify>현재 5Gbps 대역폭의 3.0 규격까지 발전한 USB 규격은 지난 2012년 7월 USB 기기의 최대 전력 공급 능력을 100W까지 늘린 Power Delivery 규격이 제정되고, CES 2013에서 제품 시연이 이뤄졌다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fusbpd01.jpg" width=500 height=296></P>
<P align=justify>USB PD는 USB 케이블만으로 최대 100W의 전력을 공급할 수 있기에 그동안 별도의 전원 어댑터가 필요했던 USB 외장 기기들을 USB 케이블만으로 활용할 수 있어, 위 시연 영상과 같이 고정식으로 이용하는 중앙 모니터를 전원 소스로 활용해 노트북을 활용하는 것도 가능하다.</P>
<P align=justify>USB가 하위 호환을 유지하면서 발전해온 것 처럼 이번 PD 규격 역시 기존 규격과 호환되지만, PD 규격을 제대로 활용하기 위해서는 이에 맞는 기기와 케이블이 필요하기에 추가 지출이 필요하며, 지난 CES 2013에서 첫 시연을 가진 만큼 실제 적용된 제품을 만나기에는 상당한 시일이 필요할 것으로 보인다.</P>
<P align=justify> </P>
<P align=center><IMG border=1 src="http://file.bodnara.co.kr/logo/logo7.html?image=%2Fhttp%3A%2F%2Ffile.bodnara.co.kr%2Fwebedit%2Fhardward%2Fcolntech%2Fusb_pd%2Fpd_00.jpg" width=500 height=334></P>
<P align=justify>아직 상용화 제품도 선보이지 않은 규격이기에 앞으로를 점치긴 조심스럽지만, 최소한 3.5" 외장 하드디스크 구동이 가능한 Profile2까지는 비교적 빠르게 보급될 것으로 전망되며, 이동이 잦은 비즈니스용 노트북이나 다수의 USB 장치를 사용하는 데스크탑 환경에서 일정 수요가 있을 것으로 예상된다.</P>
<P align=justify> </P>
<P align=justify>한편, USB-IF에서는 현재 PD 규격 이후 5Gbps인 USBs 3.0의 대역폭을 2배로 늘리기 위한 작업을 진행 중으로, 분명히 USB가 현 시점의 PC 시장에서 가장 보편적인 외장형 인터페이스임에는 분명하지만 보다 높은 성능과 기능으로 추격해오는 타 인터페이스와의 경쟁에서 살아남기 위해 노력하는 모습을 보이는데, 다음에는 어떤 곳에서 변화하는 모습을 보여줄지 기대된다.</P><BR><BR>이상호 기자 / ghostlee@bodnara.co.kr<BR><BR><BR><B>[관련기사]</B><BR><BR><A href="http://www.bodnara.co.kr/bbs/article.html?D=7&cate=5&d_category=5&num=93279" target=_new><B>SSD를 활용하는 또 다른 방법, 외장 저장장치로의 변화</B> </A><BR><A href="http://www.bodnara.co.kr/bbs/article.html?D=7&cate=2&d_category=5&num=86579" target=_new><B>성질급한 한국인을 위한 충전 기술, 기가바이트 ON/ OFF Charge</B> </A><BR><A href="http://www.bodnara.co.kr/bbs/article.html?D=7&cate=2&d_category=5&num=74052" target=_new><B>차세대 USB 3.0은 기대에 부응할 수 있을까?</B> </A><BR><A href="http://www.bodnara.co.kr/bbs/article.html?D=7&cate=30&d_category=1&num=90613" target=_new><B>USB 3.0 시대에 어울리는 스마트하드, LG 스마트하드 XE2!!</B> </A><BR><A href="http://www.bodnara.co.kr/bbs/article.html?D=7&cate=30&d_category=1&num=85866" target=_new><B>USB 3.0+7200RPM HDD+클라우드 백업, 히타치 TOURO Mobile Pro</B> </A><BR>
