简单的一个Verilog小程序，适合刚接触的人群(A simple Verilog small program, suitable for people just contact)

一种新的FIFO实现方法,verilog描述，通过modelsim 6.0 仿真，Quartue综合-FIFO realize a new method, verilog description, modelsim 6.0 through simulation, Quartue integrated

一篇关于多相滤波器的论文,讲解了关于多信道的实现与仿真。(A paper about the polyphase filter，explained about the realization of multi-channel and simulation )

基于FPGA的VHDL，can总线控制的设计与实现，在ISE下弄的。(FPGA-based VHDL, can control the design and implementation of the bus, get under the ISE' s.)

这是spi接口传输的一部分内容，本源码一共三部分，功能：spi接口的的实现即对外设的读写数据-This is the spi interface transfer part of the contents of a total of three parts of this source, function: spi interface that the realization of the read and write data to the peripheral

与单片机相比，用CPLD/FPGA器件更适合于直接对高速AD采样控制。本实验接口器件为ADC0809，根据ADC0809的工作时序使用CPLD产生该控制信号，CPLD启动AD转换后，得到的数据送至单片机并在PC机及数码管上显示AD转换结果。(Compared with the microcontroller, CPLD/FPGA devices more suitable for direct sampling control of high-speed AD. The interface of the experimental device for the ADC0809 ADC0809 Timing CPLD is used to generate the control signal, the CPLD to start the AD conversion, the data sent to the microcontroller and the AD conversion result on the PC and digital tube display)
