Planned for obsoleting in 2020.2 and not recommended for new designs.
Relacement is the LogiCORE, Video Processing Subsystem which is a license free IP and bundled with Vivado.
The Xilinx RGB to YCrCb Color Space Conversion LogiCORE™ is an optimized hardware block for converting RGB video data to the YCrCb color space.
Video system designers frequently need to convert video data between various color spaces. The Xilinx RGB to YCrCb Color-space Converter LogiCORE has built-in support for 5 formats and 3 range standards. The implementation is a simplified 3x3 constant coefficient matrix multiplier, which uses only 4 multipliers exploiting the inter-relations of RGB to YCrCb coefficients. The module is optimized to take advantage of multiply-add capabilities of XtremeDSP slices.
