一个在CPLD，EPM70128上实现的PWM控制源程序。

基于FPGA的温度计源代码，VHLL语言-Thermometer-based FPGA source code, VHLL language

此vhdl程序实现了在FPGA上构建UART通信串口。分为两部分，UART的发送端transfer和接收端receiver。需要外部根据需求提供波特率时钟。(This program implements the building vhdl UART serial interface on the FPGA. Divided into two parts, UART transfer sender and receiver receiver. Required to provide the baud clock external demand.)

基于DE2-115开发板设计的一个数字钟，能进行正常的小时、分、秒计时功能，并分别由开发板上面的数码管显示秒（60s）、分（60min）、小时（24hours）的时间。并具有手动调整时间的功能(DE2-115 board design based on a digital clock, and enables the normal hours, minutes, seconds chronograph function, and were above the development board digital display seconds (60s), points (60min), hours (24hours) time . And has a function to manually adjust the time)

通过监测工作状态实现带有IIC通讯功能的数据发送接收(to implement the sending and receiving data function of iic communication )

基本功能的cpu，自定义内存内容~了解CPU运作原理~(design of cpu,VHDL environment~)

这是rs（255，223）编码的verilog源程序。里面有：encode、decode、test－bench等文件。(This is rs (255,223) verilog source coding. Inside : encode, decode, test-bench and other documents.)

利用verlilog hdl语言编程，完成了8051内核，非常值得学习硬件描述语言的人看看！-Verlilog hdl programming language to use to complete the 8051 core, very much worth learning hardware description language of the people to see!

VHDL数字电路设计的电子书，很好的学习材料-VHDL digital circuit design of e-books, very good learning materials

这是一个利用xilinx的macroblaze将用户程序由flash读取至ddr内存的例程，关键是bootloader的写法。-This is a use of Xilinx macroblaze the user program will read from flash memory to ddr routine, the key is the wording of bootloader.
