使用Altera公司的DE2平台，使用Verilog语言描述交通灯C.

该程序是在d，t，jk触发器上用vhdl语言编写的

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.)

SPI接口的实现以及对外设的读写操作，其中包扩了几种工作方式，同时可以读取外设的版本号，传输速率可以达到2Mbps-SPI interface implementation, as well as read and write operations on the peripheral, which extended several work packages at the same time can read the version number of peripherals, transfer rate up to 2Mbps
