all passed, I was carefully designed, fully meet the requirements of beginners....

说明：  i2c module，有i2c主机和从机模块(i2c module verilog VHDL base on i2c protocol)

UART文件 包括发送器 接收器 fifo 测试文件(UART file includes a receiver transmitter fifo test files)

用verilog编写的信号调制解调程序，包括ask,fsk,qpsk的fpga实现(Prepared using verilog signal modulation and demodulation process, including ask, fsk, qpsk of fpga implementation)

基于FPGA的VHDL编程实现各种音频信号，采用的是周立功公司的fusion_startkit开发板。-FPGA-based VHDL Programming realize a variety of audio signals, are used by companies fusion_startkit weeks Ligong development board.

说明：  IIC 的Verilog实现，工程是在Xilinx的ISE9.1上实现的(IIC of the Verilog implementation project was implemented on Xilinx' s ISE9.1)

vhdl code for 8051 processor

6对于进入密码锁的按键，假设复位后七个灯显示" 0"，使用sw1、sw2 2，然后只要按下并松开sw2，七个灯上就显示" 2"，而只要按下并松开sw1，七个灯上就正确显示值" 1

CPU 5级流水线实现（加hazard处理与板级验证，板级验证带有按键消抖）(5-stage pipelined CPU (plus hazard dealing with board-level verification, board-level verification with key debounce))

这是我上大三时的电子设计题目，叫秒表的功能实现。利用ISE软件进行编程，代码是VHDL语言的，可以实现时（0-9）分（0-59）秒（0-59）即最大10小时的计数，对于不同开发板，可以适当修改代码，使之成为更加广泛的计数器。代码纯原创，请下载。

说明：  Any change to the value of Mresults in immediate and phase-continuous changes in the output frequency
