1 第二个计时器 impliomentation vhdl

数字信号处理的FPGA实现(第4版)的配套源码，极具参考价值。(The source code of the realization of digital signal processing on FPGA (4th edition) is of great reference value.)

it contains pdf file which has vhdl program of uart (universal asynchoronus receiver and transmitter). which very simple and easy to understand

非常好的SDRAM Controller 设计文档。工程必备-SDRAM Controller Design of a very good document. Works required

COUNTER 用于xilinx硬件，里面已建工程，修改ucf即可。设计由3部分组成，计数器，100M分配时钟，顶层模块，其中顶层模块包括计数器和分频器。

基于vhdl编写的贪吃蛇游戏，课程设计必备(Based on the VHDL language of the snake game, curriculum design essential)

TI公司的DAC5578驱动程序，经测试过的，CSDN资源分享(DAC5578 Driver of TI Company Tested and CSDN Resource Sharing)

快速付里叶变换子程序所需 RAM 空间以输入的首地址为基址,向增加的方向扩展(Fast Fourier Transform subroutine RAM space required to input the first address of the site was to increase the direction of expansion)

基于FPGA cyclone2的偶数分频模块，可实现自定义分频数(Based on FPGA cyclone2 even number of frequency divider module, custom frequency divider can be realized.)

adder_array的设计。加法器阵列设计，顶层模块，四步流水，21位(adder_array the design. The adder array design, top-level module, four-step pipeline, 21)

使用vhdl语言实现了数字滤波器，在Spartan-6上验证通过，最大支持240阶。源代码中滤波器为低通滤波器，可通过matlab中的fdatool工具生成滤波器系数，然后更改滤波器的通带和阻带。
