基于FPGA的抢答器程序，VHDL 语言描述。(FPGA)

实现ITU-BT1120数字并行接口的编码和解码(decode and encode ITU-BT1120 parallel digital interface)

基于VHDL开发的自动售货机系统，可实现自动售货过程中的基本功能，具有一定的代表性。-VHDL-based development of a vending machine system which can automatically process the basic functions of sales, with a certain representativeness.

这是一段写pwm的硬件程序，通过不同的占空比控制不同led灯的亮度，这样可以很好地体现vhdl的硬件代码的优点，     

详细介绍modelsim的使用方法，详细的介绍modelsim使用方法-Details on the use of ModelSim, ModelSim detail using the method

说明：  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.)

Wimax矩阵的LDPC编码器，已通过modelsim仿真测试，并前在altera的FPGA板上通过测试,码率5/6，可进入代码内部修改参数，支持2/3,3/4其他2个码率，数据吞吐量为700M(Wimax based LDPC encoder, modelsim simulation passed, also passed on altera FPGA board, code rate 5/6, also support 2/3,3/4, throughout 700m)

基于VHDL的RS232通讯程序,包含完整的源代码,锁脚文件以及下载文件,可直接下载使用(VHDL based on the RS232 communication procedures, including complete source code, locking pin, as well as download files documents can be directly downloaded using)

spansion file system包括FTL功能, 支持NAND, NOR, SPI flash.(spansion file system including FTL module, support NAND, NOR, SPI flash.)

用Vivado IPI搭建的Zynq-7000 PS到PL通信过程，使用了AXI-HP接口，利用AXI-DMA IP实现直接读写DDR的过程，软件可以配置传输尺寸。(The Zynq-7000 PS to PL communication process is built by Vivado IPI. AXI-HP interface is used, and AXI-DMA IP is used to read and write DDR directly. The software can configure the transmission size.)
