Ji Zhang · Dianzi qijian · 2014
The conversion circuit between RGB and YUV color space is widely used in video compression and image transmission. In order to reduce chip area of the conversion circuit and implement the two-way conversion with only one module circuit between RGB and YUV color space,by using PLL( Phase Locked Loop) embedded in programmable devices and pipeline algorithm,and the multiplexing structure of matrix multiplication,a new circuit structure is proposed. The simulation results showed that the maximum operating frequency of the new circuit structure with 3multipliers and 3 adders reaches 105. 89 MHz. Therefore,the new circuit structure which meets the high data transfer saves chip area greatly.
