本实验实现PS/2接口与RS

说明：  iic总线挂接在amba的apb总线上，标准接口，verilog代码的实现(iic bus attached to the amba' s apb bus, standard interfaces, verilog code implementation)

FPGA与DSP的EMIF通信，EMIF的RAM这方面相应的程序(FPGA and DSP EMIF communication)

This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file. Compression ratio is fixed for IMA-ADPCM, being 4:1.

应用背景此代码是用于执行器和传感器，可以在网络中实现一个很好的连接与其他节点和主。关键技术VHDL代码 ；可以控制位CRC校验和填料-掩模的验收规范

用游戏把子上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，等到了一定的分数，就能过关，然后继续玩下一关。

1路视频光端机的发射端，VHDL源码，使用全FPGA芯片的硬件，内建成帧、时钟、SERDES-The launch of a video PDH client, VHDL source code, use the whole FPGA chip hardware, built-in framing, clock, SERDES

全部通过，是我的精心设计，完全满足初学者的要求。-all passed, I was carefully designed, fully meet the requirements of beginners.

this program performs multiplexing and demultiplexing

these are verilg prgms
