Xilinx UltraScale™ 架構(gòu)針對(duì)要求最嚴(yán)苛的應(yīng)用，提供了前所未有的ASIC級(jí)的系統(tǒng)級(jí)集成和容量。 UltraScale架構(gòu)是業(yè)界首次在All Programmable架構(gòu)中應(yīng)用最先進(jìn)的ASIC架構(gòu)優(yōu)化。該架構(gòu)能從20nm平面FET結(jié)構(gòu)擴(kuò)展至16nm鰭式FET晶體管技術(shù)甚至更高的技術(shù)，同 時(shí)還能從單芯片擴(kuò)展到3D IC。借助Xilinx Vivado®設(shè)計(jì)套件的分析型協(xié)同優(yōu)化，UltraScale架構(gòu)可以提供海量數(shù)據(jù)的路由功能，同時(shí)還能智能地解決先進(jìn)工藝節(jié)點(diǎn)上的頭號(hào)系統(tǒng)性能瓶頸。 這種協(xié)同設(shè)計(jì)可以在不降低性能的前提下達(dá)到實(shí)現(xiàn)超過(guò)90%的利用率。 UltraScale架構(gòu)的突破包括： • 幾乎可以在晶片的任何位置戰(zhàn)略性地布置類似于ASIC的系統(tǒng)時(shí)鐘，從而將時(shí)鐘歪斜降低達(dá)50% • 系統(tǒng)架構(gòu)中有大量并行總線，無(wú)需再使用會(huì)造成時(shí)延的流水線，從而可提高系統(tǒng)速度和容量 • 甚至在要求資源利用率達(dá)到90%及以上的系統(tǒng)中，也能消除潛在的時(shí)序收斂問(wèn)題和互連瓶頸 • 可憑借3D IC集成能力構(gòu)建更大型器件，并在工藝技術(shù)方面領(lǐng)先當(dāng)前行業(yè)標(biāo)準(zhǔn)整整一代 • 能在更低的系統(tǒng)功耗預(yù)算范圍內(nèi)顯著提高系統(tǒng)性能，包括多Gb串行收發(fā)器、I/O以及存儲(chǔ)器帶寬 • 顯著增強(qiáng)DSP與包處理性能 賽靈思UltraScale架構(gòu)為超大容量解決方案設(shè)計(jì)人員開啟了一個(gè)全新的領(lǐng)域。

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.

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
