说明：  misp顶层文件，verilog实现misp架构，并且支持modelsim仿真(Verilog implements MISP architecture and supports Modelsim simulation)

黑金刚FPGA开发板使用说明文档，讲诉了NIOS和Qsys的详细开发步奏，值得学习。(KINGBOX FPGA development board documentation, recounts in detail the development of step-outs and Qsys NIOS, it is worth learning.)

Altera大学计划程序包，基于Nios II的源代码-Altera University program package, based on the Nios II source code

　M4A564/32 CPLD VHDLＡ程序，调试可用,51扩展.-M4A564/32 CPLD VHDLA procedures, debugging is available, 51 to expand.

verilog实现UART收发功能，硬件平台为spartan 6，软件平台为ise14.7(verilog implement UART rx and tx function)

VHDL硬件描述语言作业-VHDL hardware description language operations

说明：  matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.

说明：  学习VHDL可以用得上，有很多实例，可以对照着自己写一些东西(VHDL can be useful to learn, there are many examples, can be done to write something)
