一个开源mips处理器verilog 源码(wishbone interface wishbone interface)

FPGA实现SPI接口的从机功能，接收和发送全双工运行，接收到的数据以八位LED灯显示(FPGA to achieve the SPI interface the machine function, receive and send full-duplex operation, the received data to eight LED lights)

verilog vga 图像处理(verilog vga)

8051的vhdl源代码，主要针对初学者-8051 VHDL source code, mainly for beginners

通过上翻键和下翻键来设置方波信号正负脉冲宽度，利用一排流水灯来显示按键的次数，通过观察流水灯亮的盏数确定占空比（按一次上翻键亮一盏灯，流水灯全亮时占空比调到了最高或者是最低状态，按一次下翻键灭一盏灯，流水灯全灭时占空比调到了最低或者是最高状态）。(Duty cycle of LED lights and adjustable oscilloscope display code)
