在开发板EGO1上实现的图形记忆游戏，白块按下确认建，黑色块不按确认键(memory game in verilog)

自动打铃系统 附带时钟 定时打铃 整点打铃-Auto-play Ling System

代码基于VHDL语言的个文化代码有用的但是可能有错误下在是倾销心-VHDL code based on the cultural code useful but may be under the wrong heart is dumping

vhdl code for counterand detemines how counter works

说明：  this code works with spi and uart interfaces.

Verilog-RISC CPU

基于ＦＰＧＡ，实现了移位除法的功能，程序接口简单，十分好用，已经验证。-Based on the FPGA, to achieve the division of functional shift, the program interface is simple, very easy to use, has already been verified.

利用VHDL语言和模块化设计实现PCM编译码的功能，整体工程和代码全有。(PCM encode and decode by VHDL in Quartus2. )

说明：  This paper analyzes the cryptography scheme of the Trust Platform Model(TPM). The focus of the discussion would be the comparison of elliptic curve cryptography and the nowadays widely used 2048-bit RSA in evaluating which would be better suited to be used on TPM. A TPM implementation scheme based on ECC is proposed, which includes encryption and decryption schemes, signature and verification scheme, key agreement scheme. Corresponding examples of TPM commands would also be given.

本系统用于GPS中频部分的窄带滤波（AD后的数据经过LMS滤波后去掉窄带干扰，可以抑制20dB以上的干扰）(this system can be imply to anti-narrowband-jamming for GPS IF signal, it can degrade 20dB narrowband jamming)
