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.

The SDI standards are the predominant standards for uncompressed digital videointerfaces in the broadcast studio and video production center. The first SDI standard,SD-SDI, allowed standard-definition digital video to be transported over the coaxial cableinfrastructure initially installed in studios to carry analog video. Next, HD-SDI wasto support high-definition video. Finally, dual link HD-SDI and 3G-SDIdoubled the bandwidth of HD-SDI to support 1080p (50 Hz and 60 Hz) and other videoformats requiring more bandwidth than HD-SDI provides.

很多不同的廠家生產(chǎn)各種型號(hào)的計(jì)算機(jī)，它們運(yùn)行完全不同的操作系統(tǒng)，但TCP.IP協(xié)議族允許它們互相進(jìn)行通信。這一點(diǎn)很讓人感到吃驚，因?yàn)樗淖饔靡堰h(yuǎn)遠(yuǎn)超出了起初的設(shè)想。T C P / I P起源于6 0年代末美國(guó)政府資助的一個(gè)分組交換網(wǎng)絡(luò)研究項(xiàng)目，到9 0年代已發(fā)展成為計(jì)算機(jī)之間最常應(yīng)用的組網(wǎng)形式。它是一個(gè)真正的開(kāi)放系統(tǒng)，因?yàn)閰f(xié)議族的定義及其多種實(shí)現(xiàn)可以不用花錢(qián)或花很少的錢(qián)就可以公開(kāi)地得到。它成為被稱(chēng)作“全球互聯(lián)網(wǎng)”或“因特網(wǎng)(Internet)”的基礎(chǔ)，該廣域網(wǎng)（WA N）已包含超過(guò)1 0 0萬(wàn)臺(tái)遍布世界各地的計(jì)算機(jī)。本章主要對(duì)T C P / I P協(xié)議族進(jìn)行概述，其目的是為本書(shū)其余章節(jié)提供充分的背景知識(shí)。
