This application note provides a functional description of VHDL source code for a N x N DigitalCrosspoint Switch. The code is designed with eight inputs and eight outputs in order to targetthe 128-macrocell CoolRunner™-II CPLD device but can be easily expanded to target higherdensity devices. To obtain the VHDL source code described in this document, go to sectionVHDL Code, page 5 for instructions.

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).

IP核生成文件：（Xilinx/Altera 同） IP核生成器生成 ip 后有兩個(gè)文件對(duì)我們比較有用，假設(shè)生成了一個(gè) asyn_fifo 的核，則asyn_fifo.veo 給出了例化該核方式（或者在 Edit－》Language Template-》COREGEN 中找到verilog/VHDL 的例化方式）。asyn_fifo.v 是該核的行為模型，主要調(diào)用了 xilinx 行為模型庫(kù)的模塊，仿真時(shí)該文件也要加入工程。（在 ISE中點(diǎn)中該核，在對(duì)應(yīng)的 processes 窗口中運(yùn)行“ View Verilog Functional Model ”即可查看該 .v 文件）。如下圖所示。

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
