separate coefficients. In each CSC channel, the order of input remains the same – Out_A will have the same input
(In_A, In_B, In_C) as Out_B and Out_C. The coefficients will be different for each channel. Also included is an offset
value for each row of the matrix and a scaling multiple for all values. Each coefficient is 13 bit 2’s complement
resolution to ensure the signal integrity is maintained. The CSC
is designed to run at speeds up to 165Mhz, supporting
resolutions up to 1080p
at 60Hz and UXGA at 60Hz. With “any-to-any” color space support, formats such as RGB,
YUV, YCbCr, and others are supported by the CSC
.
