并行總線PATA從設計至今已快20年歷史，如今它的缺陷已經嚴重阻礙了系統(tǒng)性能的進一步提高，已被串行ATA(Serial ATA)即SATA總線所取代。SATA作為新一代磁盤接口總線，采用點對點方式進行數(shù)據(jù)傳輸，內置數(shù)據(jù)/命令校驗單元，支持熱插拔，具有150MB/s(SATA1.0)或300MB/s(SATA2.0)的傳輸速度。目前SATA已在存儲領域廣泛應用，但國內尚無獨立研發(fā)的面向FPGA的SATAIP CORE，在這樣的條件下設計面向FPGA應用的SATA IP CORE具有重要的意義。 本論文對協(xié)議進行了詳細的分析，建立了SATA IP CORE的層次結構，將設備端SATA IP CORE劃分成應用層、傳輸層、鏈路層和物理層；介紹了實現(xiàn)該IPCORE所選擇的開發(fā)工具、開發(fā)語言和所選用的芯片；在此基礎上著重闡述協(xié)議IP CORE的設計，并對各個部分的設計予以分別闡述，并編碼實現(xiàn)；最后進行綜合和測試。 采用FPGA集成硬核RocketIo MGT(RocketIo Multi-Gigabit Transceiver)實現(xiàn)了1.5Gbps的串行傳輸鏈路；設計滿足協(xié)議需求、適合FPGA設計的并行結構，實現(xiàn)了多狀態(tài)機的協(xié)同工作：在高速設計中，使用了流水線方法進行并行設計，以提高速度，考慮到系統(tǒng)不同部分復雜度的不同，設計采用部分流水線結構；采用在線邏輯分析儀Chipscope pro與SATA總線分析儀進行片上調試與測試，使得調試工作方便快捷、測試數(shù)據(jù)準確；嚴格按照SATA1.0a協(xié)議實現(xiàn)了SATA設備端IP CORE的設計。 最終測試數(shù)據(jù)表明，本論文設計的基于FPGA的SATA IP CORE滿足協(xié)議需求。設計中的SATA IP CORE具有使用方便、集成度高、成本低等優(yōu)點，在固態(tài)電子硬盤SSD(solid-State Disk)開發(fā)中應用本設計，將使開發(fā)變得方便快捷，更能夠適應市場需求。

The latest generation of Texas Instruments (TI) boardmountedpower modules utilizes a pin interconnect technologythat improves surface-mount manufacturability.These modules are produced as a double-sided surfacemount(DSSMT) subassembly, yielding a case-less constructionwith subcomponents located on both sides of theprinted circuit board (PCB). Products produced in theDSSMT outline use the latest high-efficiency topologiesand magnetic-component packaging. This providescustomers with a high-efficiency, ready-to-use switchingpower module in a compact, space-saving package. Bothnonisolated point-of-load (POL) switching regulators andthe isolated dc/dc converter modules are being producedin the DSSMT outline.TI’s plug-in power product line offers power modules inboth through-hole and surface-mount packages. The surfacemountmodules produced in the DSSMT outline use asolid copper interconnect with an integral solder ball fortheir

Agilent AN 154 S-Parameter Design Application Note S參數(shù)的設計與應用 The need for new high-frequency, solid-state circuitdesign techniques has been recognized both by microwaveengineers and circuit designers. These engineersare being asked to design solid state circuitsthat will operate at higher and higher frequencies.The development of microwave transistors andAgilent Technologies’ network analysis instrumentationsystems that permit complete network characterizationin the microwave frequency rangehave greatly assisted these engineers in their work.The Agilent Microwave Division’s lab staff hasdeveloped a high frequency circuit design seminarto assist their counterparts in R&D labs throughoutthe world. This seminar has been presentedin a number of locations in the United States andEurope.From the experience gained in presenting this originalseminar, we have developed a four-part videotape, S-Parameter Design Seminar. While the technologyof high frequency circuit design is everchanging, the concepts upon which this technologyhas been built are relatively invariant.The content of the S-Parameter Design Seminar isas follows:
