vhdl 中各种数据类型的转换实现,可以调用函数库实现

Disparity mapp code in VHDL

quartus 的220model 与 altera mf的库 用于fpga的modelsim仿真过程中添加到工程里面(the libary of 220 model and altera mf when we simulate the fpga project by modelsim)

基于分裂基的蝶型FFT，用C实现，经过测试，没有错误，可以直接拿去使用。(Based on the division of FFT butterfly type, use C implementation, tested, no error, can directly use. )

说明：  实现24小时计时，因为位数不够，这里是12进位，可自行调整进位数(Realize 24-hour timing, because the number of digits is not enough, here is 12 carry, you can adjust the carry number by yourself.)

基于ALtera公司的若干款FPGA的调试经验，对初学者有重要价值-ALtera a number of sections based on the company" s FPGA debugging experience, great value for beginners

这篇文章主要是概要的阐述了如何使用-quartusⅡ+Modelsim+synplify pro，来设计FPGA系统。-This is a summary of the main article on how to use the-quartus Ⅱ+ Modelsim+ synplify pro, to design FPGA systems.
