涉及三个文件： 源文件、 鼓励文件和验证文件，可以调节整体工作的一个基本的手电筒

这是一个计算机组成原理综合性实验：设计8位cpu。该cpu是8bit的代码，包含有4个寄存器，一个存储器，还有alu以及控制器。一共可以实现16条指令。(This is a computer composition principle of comprehensive experiment: Design 8 cpu. The cpu is 8bit code contains four registers, a memory, as well as alu and controllers. A total of 16 instructions can be achieved.)

基于SHA-1算法和DS28E01加密芯片的FPGA系统设计，该上传文件为整个设计的系统文件。Quarter软件编程的Verilog程序，包含仿真调试界面。(Design of FPGA system based on SHA-1 algorithm and DS28E01 encryption chip。)

说明：  PL 和 PS 的高效交互是 zynq 7000 soc 开发的重中之重，常常需要将 PL 端的大量数据实时送到 PS 端处理，或者将 PS 端处理结果实时送到 PL 端处理，但是各种协议非常麻烦，灵活性也比较差，直接通过 AXI 总线来读写 PS 端 ddr 的数据，这里面涉及到 AXI4 协议，vivado 的 FPGA 调试等。(The efficient interaction between PL and PS is the top priority of zynq 7000 SoC development. We often need to send a large amount of data from PL to PS for real-time processing, or send the processing results from PS to pl for real-time processing. In general, we will think of using DMA for processing, but various protocols are very troublesome and the flexibility is poor. This course explains how to use Axi directly Bus to read and write DDR data of PS terminal, which involves axi4 protocol, FPGA debugging of vivado, etc.)

FPGA实现串口发送 Verilog 语言(Serial reception FPGA Verilog language.)

说明：  用verilog编写的LVDS接口驱动程序，采用IOSERDES技术实现，经过Spartan6 FPGA调试验证，有完整的工程。(The LVDS interface driver written in verilog is implemented using IOSERDES technology. After Spartan6 FPGA debugging and verification, there is a complete project.)

64点的 FFT verilog,它是串行计算的，工作频率不到100M，计算速率很高，里面的层次很清晰。(64-point FFT verilog serial computing, the operating frequency of less than 100M, the calculated rate is high, the level inside is very clear.)
