xp2syscloclkpll
这个是讲pll的具体用法的,一般在fpga设计中都会用到 他,这个是lattice的xp2的pll的介绍,不过,fpga 都是相通的其他两家也差不多(Pll say this is the specific usage, the general design in the FPGA will use him, this is the lattice of the pll of xp2 introduction, however, fpga are connected to other two similar)

直方图均衡化fpga实现
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
