  • Xilinx UltraScale:為您未來架構而打造的新一代架構

      Xilinx UltraScale™ 架構針對要求最嚴苛的應用,提供了前所未有的ASIC級的系統級集成和容量。    UltraScale架構是業界首次在All Programmable架構中應用最先進的ASIC架構優化。該架構能從20nm平面FET結構擴展至16nm鰭式FET晶體管技術甚至更高的技術,同 時還能從單芯片擴展到3D IC。借助Xilinx Vivado®設計套件的分析型協同優化,UltraScale架構可以提供海量數據的路由功能,同時還能智能地解決先進工藝節點上的頭號系統性能瓶頸。 這種協同設計可以在不降低性能的前提下達到實現超過90%的利用率。   UltraScale架構的突破包括:   • 幾乎可以在晶片的任何位置戰略性地布置類似于ASIC的系統時鐘,從而將時鐘歪斜降低達50%   • 系統架構中有大量并行總線,無需再使用會造成時延的流水線,從而可提高系統速度和容量   • 甚至在要求資源利用率達到90%及以上的系統中,也能消除潛在的時序收斂問題和互連瓶頸   • 可憑借3D IC集成能力構建更大型器件,并在工藝技術方面領先當前行業標準整整一代   • 能在更低的系統功耗預算范圍內顯著提高系統性能,包括多Gb串行收發器、I/O以及存儲器帶寬   • 顯著增強DSP與包處理性能   賽靈思UltraScale架構為超大容量解決方案設計人員開啟了一個全新的領域。

  • Xilinx UltraScale:新一代架構滿足您的新一代架構需求(EN)

      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.

  • XAPP740利用AXI互聯設計高性能視頻系統

    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
