verilog编写的32位浮点加法器

rmii 以太网接口时序源代码，值得开发借鉴的哦(verilog hdl)

说明：  FPGA程序的top.v文件，主要实现DDS信号发生器功能，通过定时器，可简单实现输出幅值无极跳变(FPGA procedures top.v documents, the main function of DDS signal generator, through the timer can be simple to achieve the output amplitude wuji hopping)

说明：  运用VHDL描述函数发生器的各个波形，可有构成多功能函数发生器。(VHDL description of the use of various function generator waveforms, can constitute a multi-purpose function generator.)

使用verilog硬件设计语言在FPGA板子上STOPWATCH 秒表设计。(Using verilog hardware design language STOPWATCH stopwatch design on FPGA board.)

ADC-DAC transmittion works thru SPI on 25 MHZ. Used for some student project on Xilinx sprtan3a FPGA
