同步模8计数器

本代码用verilog语言配合sopc和nios实现了串口调试的目的。软件编程用C语言描述，只是比较简单的例子，适合初学者做了解用，本人亲自在EP2C8Q上实践。(The code to use verilog language sopc and nios achieved with serial debugging purposes. Software programming using C language description, but relatively simple example for beginners to do with understanding, I personally EP2C8Q on practice.)

目前最新的OVL库，里面是标准的ASSERTION模块，支持VHDL刚Verilog，最近在做AXI协议验证的时候用到，分享下(The latest OVL(open verification library),including all standard module of assertions(VHDL and Verilog). It can be used into AXI Protocl Verification. Just share with you guys.)

说明：  用于实现上位机与下位机之间通过RS232协议来进行通讯。(It is used to realize communication between upper computer and lower computer through RS232 protocol.)

这是我本人自己开发的可用于256*256大小的图像进行sobel边缘检测的vhd文件，可在QuartusII或MaxplisII下综合与与仿真，并在FPGA上测试过。能进行修改支持其他大小图像的sobeel边缘检测，同时还能实现其它的图像模块化处理算法，例如高斯滤波，平滑等。 (This is my own development vhd file, can be used for 256* 256 size image sobel edge detection under QuartusII or MaxplisII synthesis and with simulation, and tested on FPGA. Can be modified to support other sobeel size image edge detection, while still achieving other image the modular processing algorithms, such as Gaussian filtering and smoothing.)
