  • 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.

  • XAPP144 -设计CPLD多电压系统

    Today’s digital systems combine a myriad of chips with different voltage configurations.Designers must interface 2.5V processors with 3.3V memories—both RAM and ROM—as wellas 5V buses and multiple peripheral chips. Each chip has specific power supply needs. CPLDsare ideal for handling the multi-voltage interfacing, but do require forethought to ensure correctoperation.

  • XAPP713 -Virtex-4 RocketIO误码率测试器

      The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).

  • Arduino 328控制板制作音乐

       要生产音频脉冲,只要算出某一音频的周期(1/频率),可以利用定时器计时的方式得到此频率的脉冲。而Arduino平台“封装”了新的数字输出函数tone()。更简易的实现喇叭和蜂鸣器唱歌。 tone(pin, frequency),Arduino会向指定pin发送制定频率的方波,执行noTone()函数来停止。 tone(pin, frequency, duration方法多了一个参数,代表发送方波持续的时间,到时自动停止发送信号,就不需要noTone()函数。 利用tone()函数播放音乐,只需要查表了解各个音符对应的频率,还要求个人稍微能看懂音乐谱子的节拍。 物料清单 : Arduino 328控制板 1块 8Ω 0.5W的喇叭(或者蜂鸣器) 1个(ATmega328的驱动能力足够,直接拉电流就ok!) 12Ω电阻(限流) 1个 实物图:
