A video codec comprising a processor configured to generate a predicted chroma sample for a chroma block based on a plurality of reconstructed luma samples located in neighboring blocks of a corresponding reconstructed luma block and adjacent to the corresponding reconstructed luma block, and a plurality of reconstructed chroma samples located in neighboring blocks of the chroma block and adjacent to the chroma block, wherein generating the predicted chroma sample comprises computing a plurality of multipliers, wherein each of the plurality of multipliers has a bit width no greater than an input bit depth of the chroma block, and wherein generating the predicted chroma sample does not require any multiplier that has a bit width greater than the input bit depth of the chroma block.
