说明：  rgmii代码编写，实现rgmii接口功能，可进行参考设计(The rgmii code is written to realize the function of rgmii interface, which can be used for reference design)

very good code for edge detection based on vhdl programming.

这是我做UART时候做的一个发送器的源码，希望对大家有用。-This is what I did do a UART transmitter when the source and hope for all of us.

adc0809用FPGA控制的采样非常好用的实例 自己看书后终结的-ADC0809

用walsh算法实现的符号数乘法器,asic流片时,可以不用公司的付费乘法器的ip core.(algorithm using the symbols multiplier, HDL-piece quantities. it is not necessary for the company's paid Multiplier ip core.)
