xilinx 平台的SPI从接口实现源码，供参考学习(used xilinx,slave-spi interface.)

实现pwm波的输出，按键可调占空比的，可通过连接pwm输出值led灯以检测占空比的变化(To realize the output of the PWM wave, key adjustable duty ratio, but through the connection PWM output value led lamp with testing duty ratio changes )

说明：  用Verilog编写的简单的运算单元（ALU），可实现加、减、与、或、异或、非、左、右移等功能(Verilog prepared with simple arithmetic unit (ALU), can be add, subtract, and, or, exclusive-OR, non-, left, and other functions shifted to right)
