rs232串口通信代码

基于verilog的cpri接口代码，支持各种速率自由切换，量产产品实际应用代码(Cpri interface based on verilog code, support various rate free switch, production products the actual application code)

说明：  用verilog编写的ddr3芯片读写控制程序，经过调试的，可以直接拷贝。已在Xilinx Spartan6 FPGA调试验证。(The ddr3 chip read-write control program written in verilog can be copied directly after debugging. Tested and verified on Xilinx Spartan6 FPGA.)

In computer storage, multipath I/O is a fault-tolerance and performance enhancement technique whereby there is more than one physical path between the CPU in a computer system and its mass storage devices through the buses, controllers, switches, and bridge devices connecting them

说明：  amba总线桥:ahb to asb!verilog hdl文档加代码，非常全，soc(amba bus bridge: ahb to asb! verilog hdl code for the document plus a very full, soc)

fifo的代码,经过测试可以使用，很有用处，可以放心使用(a fifo module,the code has been tested and it is usefull)

FPGA测试程序，仅供测试硬件是否能够运行，主要功能是点亮运行指示灯(The main function of the test program of FPGA is to light the running indicator.)

说明：  quartusii软件仿真实验代码 双二选一(quartusii software simulation code for a pair of two elections)

how to use step motor control

说明：  实现数字频率合成实验，加载数据ram,形成波形(The experiment of digital frequency synthesis is realized, and the data RAM is loaded to form the waveform)
