本論文來(lái)自于863項(xiàng)目基于光互連自組織內(nèi)存服務(wù)體系(簡(jiǎn)稱MemoryBox)。本文主要研究Memory Box系統(tǒng)中基于可重配置計(jì)算架構(gòu)，軟硬件攜同設(shè)計(jì)方法，在XILINX VIRTEX 2 Pro FPGA上設(shè)計(jì)實(shí)現(xiàn)嵌入式系統(tǒng)。由于嵌入式系統(tǒng)是Memory Box工作的平臺(tái)，所以硬件應(yīng)具有良好的擴(kuò)展性、靈活性，軟件應(yīng)具有優(yōu)良的穩(wěn)定性。在硬件平臺(tái)選型時(shí)，我們選擇的是基于高性能Xilinx VIRTEX2 Pro的自制開(kāi)發(fā)板。嵌入式系統(tǒng)軟硬件開(kāi)發(fā)平臺(tái)選用的是Xilinx EDK、ISE。內(nèi)核移植所用的交叉開(kāi)發(fā)工具鏈為powerpc-405-linux-gnu。該交叉開(kāi)發(fā)工具鏈工作在Red Hat Enterprise LINUX．AS 4平臺(tái)下。 本論文主要包括三部分工作：首先是硬件設(shè)計(jì)，其核心是EDK和ISE設(shè)計(jì)的SOPC工程；然后是嵌入式LINUX內(nèi)核移植與調(diào)試；最后完成存儲(chǔ)管理軟件的設(shè)計(jì)。完全用硬件實(shí)現(xiàn)系統(tǒng)要求的各種存儲(chǔ)管理功能極其困難。而通過(guò)移植內(nèi)核，存儲(chǔ)管理軟件以運(yùn)行在Linux內(nèi)核上的應(yīng)用軟件的形式實(shí)現(xiàn)了其功能。存儲(chǔ)管理軟件要解決共享沖突，負(fù)載均衡，遠(yuǎn)程內(nèi)存與本地內(nèi)存的地址一致性以及對(duì)海量?jī)?nèi)存陣列的重新編址等問(wèn)題，設(shè)計(jì)出較完善的Memory Box的存儲(chǔ)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.”)
