Power Electronics And Motor Drives Advances

I am presenting this novel book on advances and trends in power electronics and motor drives to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer- sity professors, and even graduate students that my other books in this area have. Unlike the traditional books available in the area of power electronics, this book has a unique presentation format that makes it convenient for group presentations that use Microsoft’s PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is ready for presentation with the core figures. Presentations can also be organized using just selected portions of the book

基于ARM的嵌入式流媒體播放器的實現(xiàn)

近年來，網(wǎng)絡音樂，特別是網(wǎng)絡電臺的風行，受到越來越多的大眾追捧。網(wǎng)絡音樂以其及時、海量、靈活、個性化、時尚的風格，吸引了越來越多消費者的加入和眾多商家的關(guān)注。但是，作為網(wǎng)絡音樂的終端--流媒體播放器，最直接面向大眾的窗口，卻顯得單一，大部分商家只提供PC上的流媒體播放器。正出于此，本課題把目光投向那些不使用PC或者不愿長時間使用PC的用戶，為他們量身定制流媒體播放設備，讓用戶不必使用PC也可享受網(wǎng)絡音樂帶來的快樂。本課題的研發(fā)正是基于上述背景，研發(fā)支持無線網(wǎng)絡的嵌入式多功能流媒體播放設備。本課題的研究目標是實現(xiàn)一個嵌入式流媒體播放器(亦稱為InternetRadio)，Internet Radio是一個可以在家中自由移動、任意擺放的網(wǎng)絡流媒體播放設備。只要處在有網(wǎng)絡環(huán)境中，Internet Radio的音樂平臺讓用戶不必打開計算機，就能接收全球數(shù)千個不同風格、不同國家的各種類型音樂電臺。除了可以直接透過因特網(wǎng)收聽網(wǎng)絡廣播外，還可以播放儲存于計算機硬盤或MP3設備中的音樂。本系統(tǒng)采用ARM920T作為處理器，基于嵌入式Linux操作系統(tǒng)、vTuner網(wǎng)絡電臺地址數(shù)據(jù)庫、Mplayer播放器軟件和FLTK界面開發(fā)工具來實現(xiàn)。系統(tǒng)實現(xiàn)了除一般意義的音頻流媒體播放和接收調(diào)頻廣播等功能之外，還增加了本地相框和網(wǎng)絡數(shù)碼相框Flickr在線分享的流行時尚元素。本論文具體分析了系統(tǒng)的硬件平臺，主要論述了軟件的實現(xiàn)，系統(tǒng)的主要軟件功能包括bootloader和嵌入式Linux系統(tǒng)的移植，根文件系統(tǒng)的構(gòu)建，播放器軟件程序的研究、比較、移植和編寫，系統(tǒng)與網(wǎng)絡電臺地址數(shù)據(jù)庫vTuner和網(wǎng)絡相框Flickr的交互，Microwindows、Nxlib和FLTK的移植和基于FLTK的圖形界面開發(fā)，以及基于FLIK開發(fā)出良好的人機交互界面。作為項目的主要核心人員，作者負責系統(tǒng)的軟件架構(gòu)設計、Linux系統(tǒng)的移植、播放器軟件的研究和開發(fā)、GUI開發(fā)工具和圖形庫的移植、圖片播放的實現(xiàn)、用戶與設備交互的實現(xiàn)和大部分界面程序的編碼等關(guān)鍵工作。

MAX14885E VGA交叉開關(guān)電源排序

The MAX14885E, a 2:2 VGA switch, connects a VGA source to a VGA monitor. To ease direct connection to graphics controllers orthe ASIC, the MAX14885E has two supplies: VCC, a 5V ±5% supply, drives the VGA side interface; and the VL supply sets the logicswitching thresholds on the digital input pins (EN, S00, S01, S10, S11, SHA, SHB, SVA, and SVB). This application note documentsthe proper sequencing of the VCC and VL power supplies on power-up.

跟蹤和排序功能的緊湊型雙通道降壓轉(zhuǎn)換器

Typical industrial and automotive applications requiremultiple high current, low voltage power supply solutionsto drive everything from disc drives to microprocessors.For many of these applications, particularly thosethat have size constraints, the LT3501® dual step-downconverter is an attractive solution because it’s compactand inexpensive compared to a 2-chip solution. The dualconverter accommodates a 3V to 25V input voltage rangeand is capable of supplying up to 3A per channel. Thecircuit in Figure 1 produces 3.3V and 1.8V.

XAPP740利用AXI互聯(lián)設計高性能視頻系統(tǒng)

This application note covers the design considerations of a system using the performance features of the LogiCORE™ IP Advanced eXtensible Interface (AXI) Interconnect core. The design focuses on high system throughput through the AXI Interconnect core with F MAX and area optimizations in certain portions of the design. The design uses five AXI video direct memory access (VDMA) engines to simultaneously move 10 streams (five transmit video streams and five receive video streams), each in 1920 x 1080p format, 60 Hz refresh rate, and up to 32 data bits per pixel. Each VDMA is driven from a video test pattern generator (TPG) with a video timing controller (VTC) block to set up the necessary video timing signals. Data read by each AXI VDMA is sent to a common on-screen display (OSD) core capable of multiplexing or overlaying multiple video streams to a single output video stream. The output of the OSD core drives the DVI video display interface on the board. Performance monitor blocks are added to capture performance data. All 10 video streams moved by the AXI VDMA blocks are buffered through a shared DDR3 SDRAM memory and are controlled by a MicroBlaze™ processor. The reference system is targeted for the Virtex-6 XC6VLX240TFF1156-1 FPGA on the Xilinx® ML605 Rev D evaluation board

WP150-解決數(shù)兆兆位及更高的網(wǎng)絡挑戰(zhàn)

In today’s world of modular networking and telecommunications design, it is becomingincreasingly difficult to keep alignment with the many different and often changing interfaces,both inter-board and intra-board. Each manufacturer has their own spin on the way in whichdevices are connected. To satisfy the needs of our customers, we must be able to support alltheir interface requirements. For us to be able to make products for many customers, we mustadopt a modular approach to the design. This modularity is the one issue that drives the majorproblem of shifting our bits from one modular interface to another.
