分别用分频比交错法及累加器分频法完成非整数分频器设计。-Points were staggered method and frequency than the frequency accumulator law to complete the design of non-integer divider.

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.)

说明：  通过SPI接口实现FPGA和MCP2515独立CAN芯片通信，功能使用modelsim仿真，实现了配置、接收、发送功能。(The communication between FPGA and MCP2515 independent can chip is realized by SPI interface. The function is simulated by Modelsim, and the function of configuration, receiving and sending is realized.)

说明：  使用FPGA实现中值滤波算法，能够使数据直接使用该系统对数据进行中值滤波。(FPGA is used to realize the median filtering algorithm, which can make the data directly use the system for median filtering.)
