RGB 与YCbCr 颜色空间可以相互转化(RGB and YCbCr color space can be transformed into each other)

这代码是 I2C 子设备。给定的 I2C 设备是异步的可以用来通电，数字逻辑的其余部分。也可以用作 SMBus 设备。

用PrimeTime的技巧，解决复杂时钟问题。(The world of telecommunications chips is full of messy clocking situations. This paper will cover the tricks and tehniques that author Paul Zimmer has developed to avoid the need to pour over reams of timing reports looking for problems. Best paper winner at SNUG San Jose 2001!)

在fpga上实时实现图像的直方图均衡化，有效利用fpga芯片的片内资源，不需要添加片外的存储芯片。本代码是基于ycbcr处理的，其实只对亮度分量进行直方图均衡化，之后同步cb，cr颜色分量，避免偏色问题！代码接口为y,cb,cr,以及行场信号，hs,vs,de.最终的处理效果可以达到在pc机上的效果，但是比pc块很多，几乎可以实时完成处理

应用背景此代码是移行为模型和添加乘数随着乘数和被乘数参数比特宽度关键技术Verilog 2001和Xilinx的Spartan 6 FPGA板试验台

说明：  这是本人曾经参与的一个DDR controller接口项目，主要是FPGA rtl实现，仅供参考。(This is a DDR controller interface project that I once participated in, mainly implemented by FPGA RTL, for reference only.)
