i2c配置SAA7113，非常有用的程序，做视频采集类必看(i2c configure SAA7113)

verilog源代码，实现两种方法的模3运算。(verilog source code，to implement the calculation of mod-3 by two means.)

功能说明：实现倒计时、按键可实现暂停/继续、时间设置、清零 附加说明：倒计时到零时，蜂鸣并闪烁；暂停时，时间分隔符闪烁；设置时，当前设置位闪烁。  按键说明  非设置状态：      数字显示不为0时，按enter键在计时与暂停状态进行切换，长按秒进入设置状态，长按5秒清零并进入暂停状态;  全为零时按enter键进入设置状态;  设置状态：      按enter进入计时状态  长按一秒置零  长按5秒置零并进入暂停状态   

说明：  verilog标准语法，还有很多的样例参考，学习的好资料。(Verilog standard grammar, there are many examples for reference, good learning materials.)

RS 编码和解码Verilog Code, 实现了RS（204,188)的编码和译码；(RS Coding and Decoding Verilog code，　implement RS（204,188) )

Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.

说明：  FPGA控制外边led，并实现跑马灯等多种效果，用户可以自行控制(FPGA control outside led)

这是一个二进制的最简单分频器，是一个简短的fpga代码，用verilog书写(This is the most simple of a binary frequency divider, the fpga is a short code, written in verilog)
