这是一个AMBA APB桥实现VHDL。这包括主人，奴隶和试验台试验桥。我已经测试功能。

说明：  fpga实现相关滤波算法中的CSK算法，采用仿真的方式验证结果 fpga是xilinx 仿真工具是vivado2018.2 语言是verilog(The CSK algorithm is implemented in FPGA, and the results are verified by simulation FPGA is Xilinx The simulation tool is vivado 2018.2 Language is Verilog)

本人编写的FPGA光电编码器输入模块,没有实验,但仿真基本实现,希望有参考价值.(FPGA optical encoder input module, there is no experimental, but simulation technology, hope to have reference value.)
