Abstract: An apparatus to facilitate utilizing structured sparsity in systolic arrays is disclosed. The apparatus includes a processor comprising a systolic array to receive data from a plurality of source registers, the data comprising unpacked source data, structured source data that is packed based on sparsity, and metadata corresponding to the structured source data; identify portions of the unpacked source data to multiply with the structured source data, the portions of the unpacked source data identified based on the metadata; and output, to a destination register, a result of multiplication of the portions of the unpacked source data and the structured source data.

Abstract: Embodiments provide for a graphics processing apparatus comprising a graphics processing unit having fixed point logic to convert YUV encoded image data to RGB encoded image data. In one embodiment the fixed point logic includes a set of fixed function logic circuits to compute a set of fixed point approximations of specified floating point color space conversion coefficients during the conversion of the YUV encoded image date to the RGB encoded image data.
