摘　　要：RGB与YUV色彩空间转换是视频处理系统的重要部分,该转换是对后级信号处理的基础.首先给出色彩空间定义与转换公式,针对彩色空间一般的实现方法,提出一种改进的逻辑设计.它仅用4个乘法器来实现设计,从而节省了近一半的逻辑资源.并通过对乘法器采用CSD码和Wallace树进行优化,进一步减少逻辑资源,以及提高了整个模块的最高运行速度.整个电路的功能通过了Verilog-XL的仿真.RGB Color Space to YUV Color Space conversion is very important in the video processing.The conversion is the foundation of later signal processing.Firstly,the definition of Color Space and the conversion equations are introduced,and an improved circuit architecture is presented.The architecture consists of four multipliers,saves approximately half in logic resources.The multiplier of circuit optimized by CSD coding and Wallace tree,effectively saves logic resources,and enhances the frequency.The function o...
