AB相编码器解码接口_PWM输出SOPC方案及其在运动控制卡和伺服驱动器中的应用-AB phase encoder decoder interface _PWM output SOPC program and its application in motion control card and servo drive

将运动控制卡的方向信号与脉冲信号转换为两路正交方波信号信号（模拟光栅信号）-The direction of the signal and the pulse signal is converted motion control card for two orthogonal square wave signal signal (analog signal raster)

这是PCI运动控制卡的核心代码，我的一个项目程序，很好用，verilog 语言编写。-This is a PCI motion control card core code, I have a project program, easy to use, verilog language.
