一篇比较好的spi接口的vhdl实现的参考

这个是用VHDL实现FPGA对FLASH的读写。(This is achieved using VHDL FLASH FPGA to read and write.)

讲述了dds直接数字频率合成的基本原理，同时用ＶＨＤＬ语言编写dds原代码用于生成正弦波，并在ISE开发平台进行仿真和MATLAB验证正弦波输出结果-described dds direct digital frequency synthesis of the basic tenets addition to the use of VHDL prepared dds source used to produce sine, and ISE development platform for simulation and verification MATLAB sine wave output

用NiosII实现的数字钟，经过本人测试运行正常，开发环境：QuartusII6.0和NiosII IDE6.0-NiosII achieved with digital clock, after I run the normal tests, development environment: QuartusII6.0 and NiosII IDE6.0

this is the vhdl code for the arithmetic logic unit.enjoy!

用VHDL语言编写的AT24C02程序，并用数码管显示，本程序已经经过本人测试过，很好用-The AT24C02 is available VHDL language program, and use digital tube display, this procedure has been tested himself, very good to use--

Simulating the functions of POC.(Simulating the functions of POC. In VHDL, with ISE.)

此程序为串行通信程序,采用verilog语言编写的,经过仿真验证已经通过.-This procedure for the serial communication procedures, the use of Verilog language, after simulation has been adopted.

这是我的VHDL格式的电子密码锁源程序，请站长审核啊-This is my VHDL source code format of the electronic lock, please review ah owners

Parallel to Serial converter Module

说明：  该模块实现了FPGA的uart串口收发功能(The module realizes UART serial port transceiver function of FPGA)
