UART的源（格版）

FPGA做波形发生器，产生8种波形，包括三角波，正弦波，锯齿波，方波等。(FPGA is used as waveform generator,Generate 8 waveforms, including triangle, sine, sawtooth, square, etc.)

做EDA的，就不用介绍这个文件了吧，IEEE1364标准（开放）。-done, would not have introduced the document on the bar, IEEE1364 standard (open).

说明：  xilinx 平台的SPI从接口实现源码，供参考学习(used xilinx,slave-spi interface.)

在FPGA开发板上用VHDL语言实现了贪吃蛇游戏，开发软件为quartus 2.这是详细的实验报告，包括源码(Snake game with VHDL FPGA development board, software development quartus 2 This is a detailed experimental report, including the source)

这是我准备电子设计大赛时，用VHDL写的一个自动打铃系统，很好的学习资料。-This is when I am going to Electronic Design Contest, use VHDL to write an automatic bell playing system, a very good learning materials.

异步fifo实现，通过双口ram实现异步fifo(Asynchronous FIFO implementation, through dual port RAM to achieve asynchronous FIFO)

用verilog编写的lms算法。可实现自适应滤波功能(Lms algorithm written in verilog. Adaptive filtering can be achieved)

verilog写的数字频率计的选择模块,用与显示的选择-written in Verilog digital frequency meter option module, used and display options

code for fft non synthesisable in xilinx ise

用FPGA实现dct变换。verilog语言实现，在quartus9.0中验证，含整个工程(dct transform verilog language in quartus9.0 verify, with the entire project)
