  • Xilinx UltraScale:新一代架构满足您的新一代架构需求(EN)

      中文版详情浏览: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.

  • 使用Nios II软件构建工具

     使用Nios II软件构建工具 This chapter describes the Nios® II Software Build Tools (SBT), a set of utilities and scripts that creates and builds embedded C/C++ application projects, user library projects, and board support packages (BSPs). The Nios II SBT supports a repeatable, scriptable, and archivable process for creating your software product. You can invoke the Nios II SBT through either of the following user interfaces: ■ The Eclipse™ GUI ■ The Nios II Command Shell The purpose of this chapter is to make you familiar with the internal functionality of the Nios II SBT, independent of the user interface employed.

  • Nios II定制指令用户指南

         Nios II定制指令用户指南:With the Altera Nios II embedded processor, you as the system designer can accelerate time-critical software algorithms by adding custom instructions to the Nios II processor instruction set. Using custom instructions, you can reduce a complex sequence of standard instructions to a single instruction implemented in hardware. You can use this feature for a variety of applications, for example, to optimize software inner loops for digital signal processing (DSP), packet header processing, and computation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphical user interface (GUI) used to add up to 256 custom instructions to the Nios II processor. The custom instruction logic connects directly to the Nios II arithmetic logic unit (ALU) as shown in Figure 1–1.
