altera 公司的15IP源码 亲自测试还不错 有DIV, CONTER

SDRAM控制器源码，内含完整的控制器verilog源代码和测试代码，超值哈。-This readme file for the SDR SDRAM Controller includes information that was not incorporated into the SDR SDRAM Controller White Paper v1.1.

完成的是RS422信号的计数功能，并产生一定的触发信号-RS422 signals the completion of the count function, and produce a certain trigger signals

计数器是数字系统中使用最多的时序电路，它不仅能用于对时钟脉冲计数，还可以用于分频、定时、产生节拍脉冲和脉冲序列以及进行数字运算等。(Counter is the most frequently used sequential circuit in digital system. It can be used not only for counting clock pulses, but also for frequency division, timing, generating beat pulses and pulse sequences, and performing digital operations.)

说明：  这个事VHDL基础知识，内面主要内容是编码器的插V过程，值得下载学习！(it is really useful for those who never touch it!)

应用背景FPGA原型的VHDL例子提供一系列清晰，易于遵循的快速代码开发模板；大量的实际例子来说明和强化的概念和设计技术；现实可实施的项目和测试在Xilinx原型板；深入探索和Xilinx PicoBlaze软核微处理器。关键技术本书采用“做中学”介绍VHDL和FPGA技术的概念和设计人员通过一系列的实验方法。
