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

近年来，网络音乐，特别是网络电台的风行，受到越来越多的大众追捧。网络音乐以其及时、海量、灵活、个性化、时尚的风格，吸引了越来越多消费者的加入和众多商家的关注。但是，作为网络音乐的终端--流媒体播放器，最直接面向大众的窗口，却显得单一，大部分商家只提供PC上的流媒体播放器。正出于此，本课题把目光投向那些不使用PC或者不愿长时间使用PC的用户，为他们量身定制流媒体播放设备，让用户不必使用PC也可享受网络音乐带来的快乐。 本课题的研发正是基于上述背景，研发支持无线网络的嵌入式多功能流媒体播放设备。本课题的研究目标是实现一个嵌入式流媒体播放器(亦称为InternetRadio)，Internet Radio是一个可以在家中自由移动、任意摆放的网络流媒体播放设备。只要处在有网络环境中，Internet Radio的音乐平台让用户不必打开计算机，就能接收全球数千个不同风格、不同国家的各种类型音乐电台。除了可以直接透过因特网收听网络广播外，还可以播放储存于计算机硬盘或MP3设备中的音乐。 本系统采用ARM920T作为处理器，基于嵌入式Linux操作系统、vTuner网络电台地址数据库、Mplayer播放器软件和FLTK界面开发工具来实现。系统实现了除一般意义的音频流媒体播放和接收调频广播等功能之外，还增加了本地相框和网络数码相框Flickr在线分享的流行时尚元素。本论文具体分析了系统的硬件平台，主要论述了软件的实现，系统的主要软件功能包括bootloader和嵌入式Linux系统的移植，根文件系统的构建，播放器软件程序的研究、比较、移植和编写，系统与网络电台地址数据库vTuner和网络相框Flickr的交互，Microwindows、Nxlib和FLTK的移植和基于FLTK的图形界面开发，以及基于FLIK开发出良好的人机交互界面。作为项目的主要核心人员，作者负责系统的软件架构设计、Linux系统的移植、播放器软件的研究和开发、GUI开发工具和图形库的移植、图片播放的实现、用户与设备交互的实现和大部分界面程序的编码等关键工作。

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.

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.

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

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.
