基于FPGA的数字系统设计,包含原理、工程应用和案例。(FPGA-based digital system design, including theory, engineering applications and cases.)

FPGA开发超声波测距，可改写工业探伤或倒车测距等系统，quartus2下选择EP2C5Q208C8（CycloneⅡ） 支持目前淘宝上能买到的所有4-5针超声波模块 应用cycloneⅡ自带除法模块 开发板为有光技术YG2.1 生成电路规模较小 ！！注意：移植程序仅需重新约束数码管和超声波模块的针脚 (Ultrasonic Ranging FPGA development, industrial inspection or reverse rewritable ranging systems, EP2C5Q208C8 (CycloneⅡ) under quartus2 4-5 needle ultrasonic module supports all currently scouring the treasure can buy Applications cycloneⅡ own division module Development board bright technical YG2.1 Small scale generating circuit ! ! Note: The migration program only re-constraint digital and ultrasonic modules Pin)

通过matlab对于声音进行处理，实现FFT，均值，方差，中值滤波，自相关分析，白噪声等处理(Matlab sound processing, FFT, mean, variance, median filtering, autocorrelation analysis, white noise and processing)

VHDL语言编写的计数器程序，实现1到9999计数，并动态扫描显示，带清零和暂停功能，课上作业自编程序-VHDL language of the counter program to achieve 1-9999 counts, and the dynamic scan showed, with Clear and suspension of functions, classes, on a self-compiled programs

Verilog分频程序原理讲解及代码.偶数倍分频奇数倍分频的原理和方法(Verilog divide the program explain the principle and code an even multiple of odd multiple of the principle of divide and divide)

说明：  SDIO 接口，实现SD卡的控制器功能，带有详细的注释(SDIO Interface,to realize the controller of SD Card,and have detail description.)

这是用verilog语言实现的1024点ff程序t-This is achieved using Verilog 1024 language ff procedures point t

用verilog语言写的简单的键盘扫描代码，适合初学者，用alter的软件编写的程序代码。(Using verilog language to write simple keyboard scan code, suitable for beginners, with alter software program written code.)

说明：  verilog语言书写，单周期CPU源码(single period CPU)
