Summary
This application note describes the implementation of a YCrCb color space to an RGB Color space conversion circuit necessary in many video designs. The reference design files include RTL VHDL code defining an optimized structure using only five multipliers to implement the YCrCb to RGB transformation. Source files in compilation order are: 1. GenXlib_util.vhd 2. GenXlib_arch.vhd 3. color_space_pkg.vhd 4. Xil_YCrCb2RGB.vhd A System Generator token encapsulating the HDL code is also available for System Generator users. A System Generator testbench is also provided to visually inspect output results. The code is parameterizable
