The STi7200 is a new generation, high-definition set-top box/DVD decoder chip, and provides very high performance for low-cost HD systems. With enhanced performance over the STx7109, it includes both Windows Media Video 9 and H.264 video decoders for new, low bitrate applications. The STi7200 is able to decode two HD programs

本论文来自于863项目基于光互连自组织内存服务体系(简称MemoryBox)。本文主要研究Memory Box系统中基于可重配置计算架构，软硬件携同设计方法，在XILINX VIRTEX 2 Pro FPGA上设计实现嵌入式系统。由于嵌入式系统是Memory Box工作的平台，所以硬件应具有良好的扩展性、灵活性，软件应具有优良的稳定性。在硬件平台选型时，我们选择的是基于高性能Xilinx VIRTEX2 Pro的自制开发板。嵌入式系统软硬件开发平台选用的是Xilinx EDK、ISE。内核移植所用的交叉开发工具链为powerpc-405-linux-gnu。该交叉开发工具链工作在Red Hat Enterprise LINUX．AS 4平台下。 本论文主要包括三部分工作：首先是硬件设计，其核心是EDK和ISE设计的SOPC工程；然后是嵌入式LINUX内核移植与调试；最后完成存储管理软件的设计。完全用硬件实现系统要求的各种存储管理功能极其困难。而通过移植内核，存储管理软件以运行在Linux内核上的应用软件的形式实现了其功能。存储管理软件要解决共享冲突，负载均衡，远程内存与本地内存的地址一致性以及对海量内存阵列的重新编址等问题，设计出较完善的Memory Box的存储管理模型。

Portable, battery-powered operation of electronic apparatushas become increasingly desirable. Medical, remotedata acquisition, power monitoring and other applicationsare good candidates for battery operation. In some circumstances,due to space, power or reliability considerations,it is preferable to operate the circuitry from a single 1.5Vcell. Unfortunately, a 1.5V supply eliminates almost alllinear ICs as design candidates. In fact, the LM10 opamp-reference and the LT®1017/LT1018 comparators arethe only IC gain blocks fully specifi ed for 1.5V operation.Further complications are presented by the 600mV dropof silicon transistors and diodes. This limitation consumesa substantial portion of available supply range, makingcircuit design diffi cult. Additionally, any circuit designedfor 1.5V operation must function at end-of-life batteryvoltage, typically 1.3V. (See Box Section, “Componentsfor 1.5V Operation.”)
