搜集的一些国外经典Verilog代码，很经典，实用，适合于一些有一定verilog编程经验的同道中人学习。中间有一些注释，便于理解和分析，很好用。其中一些例子堪称经典，大家一起学习，共勉！

所有的单片机都会涉及到232 或者485通讯,而通讯中又不可避免的出现错误.本例就给出了一个现成的校验软件.完成串口通讯,并且进行crc,累加和,异或和等效验结果-All of the single-chip will be 232 or 485 relating to communications, and communications also inevitable error. In this case on a given off-the-shelf software validation. The completion of serial communications, and to carry out crc, cumulative and, XOR and equivalent examination results

利用该源代码可以实现在DE2的板子上进行USB画笔的实验-use of the source code can be achieved in the board Dictyophora USB brush on the experiment

给出Linux 环境下USB驱动的模块层次结构，包括主控制器驱动、USB 核心驱动和USB设备驱动程序组成，以及USB 接口摄像头驱动模块的层次结构，对底层usbvideo 模块进行分析，对usbvideo 中的函数进行了分类，修正其设计上的一个缺 陷，给出上层微型驱动的实现，最后通过移植USB 摄像头驱动程序到三星公司的SMDK2410 开发板的试验成功，使该驱动成 功应用在基于Linux 的嵌入式系统上。-Given Linux environment USB drive module hierarchy, including the host controller driver, USB core driver and USB device drivers, as well as camera USB interface drive module hierarchy of the underlying module usbvideo analysis, in usbvideo function of classification, to amend the design of a defect, given the realization of the upper micro-drive, and finally through the transplantation driver USB camera to Samsung SMDK2410 development board of the experiments are successful, so successful application of the driver in the Linux-based embedded systems.
