xilinx Zynq-7000 EPP產品簡介

The Xilinx Zynq-7000 Extensible ProcessING Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

XAPP807-封裝最小的三態以太網MAC處理引擎

The Tri-Mode Ethernet MAC (TEMAC) UltraController-II module is a minimal footprint,embedded network ProcessING engine based on the PowerPC™ 405 (PPC405) processor coreand the TEMAC core embedded within a Virtex™-4 FX Platform FPGA. The TEMACUltraController-II module connects to an external PHY through Gigabit Media IndependentInterface (GMII) and Management Data Input/Output (MDIO) interfaces and supports tri-mode(10/100/1000 Mb/s) Ethernet. Software running from the processor cache reads and writesthrough an On-Chip Memory (OCM) interface to two FIFOs that act as buffers between thedifferent clock domains of the PPC405 OCM and the TEMAC.

NIOSII用戶定制指令

With the Altera Nios II embedded processor, you as the system designercan accelerate time-critical software algorithms by adding custominstructions to the Nios II processor instruction set. Using custominstructions, you can reduce a complex sequence of standard instructionsto a single instruction implemented in hardware. You can use this featurefor a variety of applications, for example, to optimize software innerloops for digital signal ProcessING (DSP), packet header ProcessING, andcomputation-intensive applications. The Nios II configuration wizard,part of the Quartus® II software’s SOPC Builder, provides a graphicaluser interface (GUI) used to add up to 256 custom instructions to theNios II processor

orcad無法輸出網表問題解決方法

ORCAD在使用的時候總會出現這樣或那樣的問題…但下這個問題比較奇怪…在ORCAD中無法輸出網表…彈出下面的錯誤….這種問題很是奇怪…Netlist Format: tango.dllDesign Name: D:\EDA_PROJECT\PROTEL99SE\YK\SV3200\MAIN.DSNERROR [NET0021] Cannot get part.[FMT0024] Ref-des not found. Possible Logical/Physical annotation conflict.[FMT0018] Errors ProcessING intermediate file找了一天沒找到問題…終于在花了N多時間后發現問題所在…其實這個問題就是不要使用ORCAD PSPICE 庫里面的元件來畫電路圖…實際中我是用了PSPICE里面和自己制作的二種電阻和電容混合在一起…就會出現這種問題…
