A color space is a mathematical representation of a set of colors. The three most popular color models are:

• RGB most common in computer graphics, or R’G’B’ (gamma corrected)
• YIQ, YUV, YCrCb common in video systems
• CMYK mostly used in color printing

These color spaces are directly related to the intuitive notions of luminance and chrominance and there may be a need to change from one color space to a second.  The RGB to YCrCb color-space converter is used in a wide rage of imaging applications.  This IP Core is a simplified 3x3 matrix multiplier converting 3 input color samples to 3 output samples in a single CLK cycle. The optimized structure uses only 4 multipliers or DSP48 slices taking advantage of the dependencies between coefficients in the conversion matrix of most YCrCb or YUV to RGB standards.
