3X3矩阵乘法的VHDL程序！对初学者有很大帮助！

说明：  XC7A35TCSG324-1的Verilog频率计程序，支持十分频，支持切换内外信号输入(Verilog frequency meter program of xc7a35tcsg324-1 supports decadal frequency division and switching internal and external signal input)

实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 --A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 --各种波形的线形叠加输出。 (Achieve the four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency and amplitude controlled output (square wave- A duty cycle is controlled), can store arbitrary waveform feature data and can to reproduce the waveform, it can perform- all kinds of linear superposition of the output waveform.)

EDA常用双LED显示译码程序，将四位二进制数译码为七位对应于LED7位输入的高低电平信号-EDA common dual LED display decoding procedure will be four binary decoding for seven LED7 spaces corresponding to the input signal circuits

说明：  一个具备bp协议典型功能的数据传输系统（超时重传机制以及托管传输）包含五个节点(A data transmission system with typical functions of BP protocol (Overtime retransmission mechanism and managed transmission) consists of five nodes)

路由器是Noc的重要组成部分。本文实现了一个简单的Noc路由器。该路由器的主要单元包括FIFO缓冲区、路由单元、控制单元、交叉开关和仲裁单元。在这种情况下，使用XY路由算法。这里没有使用流量控制机制。仲裁器的输出决定了纵横开关的选择线。这里5到1个mux构成一个纵横制交换机。有5个仲裁单位。存在5个路由逻辑单元。每个端口都有自己的路由单元。路由单元的输出包括本地、北、南、东和西。ie输出是一个5位向量。此输出的第0位表示本地端口，第1位表示北，第2位表示南等。对于本地仲裁器输入，是所有t的第0位

GAL16V8(仿真74LS138),试验通过。包括able及jed文件。对pcb印板设计时，对简化走线特别有用。简单的修改GAL16V8程序，可灵活地进行地址译码修改。(GAL16V8 (simulation 74LS138), test passed. Including the able and jed file. Printed on the pcb board design, especially useful to simplify alignment. Simple modifications GAL16V8 program, the flexibility to change the address decoding.)

ssb的调制与解调，包括信号的产生、乘法器、加噪、BPF、解调等部分。(ssb modulation and demodulation, signal generation, multiplier, adding noise, BPF, demodulation section.)
