Abstract:

This paper designs a simple method for color space conversion in FPGA.First,the decimal coefficients in transformation matrix are changed into integers through a left shift operation,then nine adders and nine constant coefficient multipliers are instantiated to implement the conversion in parallel pipelines with Verilog HDL,and finally the correct values are obtained through a right shift operation.This method is simulated with Modelsim and verified on Xilinx FPGA hardware platform by converting RGB to YC_bC_r422.
