單片機原理與應用《課程簡介》：單片機已成為電子系統中進行數據采集、信息處理、通信聯絡和實施控制的重要器件。通常利用單片機技術在各種系統、儀器設備或裝置中，形成嵌入式智能系統或子系統。因此，單片機技術是電類專業特別是電子信息類學生必須具備的基本功。本課程以51系列單片機為模型，主要向學生介紹單片機的基本結構、工作原理、指令系統與程序設計、系統擴展與工程應用。作為微機原理與接口技術的后續課程，本課程強調實踐環節，側重系統構成與應用設計。力求通過實踐環節，軟、硬結合，培養初步的單片機開發能力，并使其前導課程講授的基本概念得到綜合與深化。由于課時的限制，綜合性的應用設計安排在后續課程《微機應用系統設計》中進行。 課 程 內 容：第一章 單片微型計算機概述單片機的發展與應用 MCS-51系列單片機簡介第二章 MCS-51系列單片機結構MCS-51單片機基本結構 CPU 時序簡介 存儲器空間結構 片內RAM與SFR時鐘電路與復位電路 并行I/O口與總線擴展第三章 MCS-51單片機指令系統指令系統簡介數據傳送指令 數據處理指令 位處理指令 程序控制指令匯編語言程序設計方法 程序調試的常用方法第四章 SCB-I 單片單板機SCB-I 單片單板機結構簡介 監控系統簡介SCB-I 單片單板機的基本操作 第五章 單片機常用接口電路的軟、硬件設計LED顯示接口電路與應用編程鍵盤接口電路與應用編程計數器/定時器工作原理及其應用編程MCS-51中斷系統及其應用編程8255擴展并行接口及其應用編程串行通信接口及其應用編程A/D與D/A轉換接口及其應用編程*第六章 單片機應用系統設計舉例第七章 單片機開發工具簡介* 加“*”為選講內容教學要求：1、 了解單片機的一般性概念及單片機技術的發展。2、 掌握51系列單片機的基本結構與工作原理。3、 掌握51系列單片機的指令系統與程序設計的基本方法。4、 以單片單板機為樣板，掌握51系列單片機的系統擴展設計。5、 通過實驗，掌握單片機常用接口電路的軟硬件設計及其應用。6、 以上為本課程的基本要求。作為提高要求，對有能力、有興趣的學生，若能較快地完成基本實驗，可在規定課時內安排有一定難度的綜合性實驗，以提高其應用設計的能力。 課時安排和考核方式：1、 講課40學時，實驗20學時，課內外學時比 1:2 ；（實驗從第七周開始，7個基本實驗，選做1個綜合實驗）2、 考核方式平時考查 20實驗考核 40（含實驗過程、實驗驗收與實驗報告）期末筆試 40參考書：《MCS-51單片機應用設計》 張毅剛 等編 哈爾濱工業大學出版社《MCS-51系列單片機原理及應用》 孫涵芳 徐愛卿 編著 北京航空航天大學出版社《單片微機與測控技術》 趙秀菊 等編 東南大學出版社《單片微型機原理、應用與實驗》 張友德 等編 復旦大學出版社 《單片機實驗》 肖璋 雷兆宜 編 暨南大學講義

中文版詳情瀏覽：http://www.elecfans.com/emb/fpga/20130715324029.html Xilinx UltraScale:The Next-Generation Architecture for Your Next-Generation Architecture The Xilinx® UltraScale™ architecture delivers unprecedented levels of integration and capability with ASIC-class system- level performance for the most demanding applications. The UltraScale architecture is the industr y's f irst application of leading-edge ASIC architectural enhancements in an All Programmable architecture that scales from 20 nm planar through 16 nm FinFET technologies and beyond, in addition to scaling from monolithic through 3D ICs. Through analytical co-optimization with the X ilinx V ivado® Design Suite, the UltraScale architecture provides massive routing capacity while intelligently resolving typical bottlenecks in ways never before possible. This design synergy achieves greater than 90% utilization with no performance degradation. Some of the UltraScale architecture breakthroughs include: • Strategic placement (virtually anywhere on the die) of ASIC-like system clocks, reducing clock skew by up to 50% • Latency-producing pipelining is virtually unnecessary in systems with massively parallel bus architecture, increasing system speed and capability • Potential timing-closure problems and interconnect bottlenecks are eliminated, even in systems requiring 90% or more resource utilization • 3D IC integration makes it possible to build larger devices one process generation ahead of the current industr y standard • Greatly increased system performance, including multi-gigabit serial transceivers, I/O, and memor y bandwidth is available within even smaller system power budgets • Greatly enhanced DSP and packet handling The Xilinx UltraScale architecture opens up whole new dimensions for designers of ultra-high-capacity solutions.

頻譜分析儀的主要工作原理 接收到的中頻模擬信號經過A/D轉換為14位的數字信 號，首先對數字信號進行數字下變頻（DDC），得到I路、Q路信號，然后根據控制信號對I路、Q路信號進行抽取濾波，使用CIC抽取濾波器完成，然后在分 別對I路、Q路信號分別進行低通濾波，濾波器采用FIR濾波器和半帶濾波器相結合的方式，然后對信號進行加窗、FFT（對頻譜進行分析時進行FFT運算， 對功率譜進行分析時不進行FFT運算）、I路和Q路平方求和、求平均。最后將輸出的數據送入到DSP中進行顯示與控制的后續處理。

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

XAPP520將符合2.5V和3.3V I/O標準的7系列FPGA高性能I/O Bank進行連接 The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems

摘要: 串行傳輸技術具有更高的傳輸速率和更低的設計成本, 已成為業界首選, 被廣泛應用于高速通信領域。提出了一種新的高速串行傳輸接口的設計方案, 改進了Aurora 協議數據幀格式定義的弊端, 并采用高速串行收發器Rocket I/O, 實現數據率為2.5 Gbps的高速串行傳輸。關鍵詞: 高速串行傳輸; Rocket I/O; Aurora 協議 為促使FPGA 芯片與串行傳輸技術更好地結合以滿足市場需求, Xilinx 公司適時推出了內嵌高速串行收發器RocketI/O 的Virtex II Pro 系列FPGA 和可升級的小型鏈路層協議———Aurora 協議。Rocket I/O支持從622 Mbps 至3.125 Gbps的全雙工傳輸速率, 還具有8 B/10 B 編解碼、時鐘生成及恢復等功能, 可以理想地適用于芯片之間或背板的高速串行數據傳輸。Aurora 協議是為專有上層協議或行業標準的上層協議提供透明接口的第一款串行互連協議, 可用于高速線性通路之間的點到點串行數據傳輸, 同時其可擴展的帶寬, 為系統設計人員提供了所需要的靈活性[4]。但該協議幀格式的定義存在弊端,會導致系統資源的浪費。本文提出的設計方案可以改進Aurora 協議的固有缺陷,提高系統性能, 實現數據率為2.5 Gbps 的高速串行傳輸, 具有良好的可行性和廣闊的應用前景。
