Abstract

Systolic array-based systems and methods for performing block matching in motion compensation. A target pixel block is loaded into a systolic array. A matching sized block of a reference search space is loaded into the array, row by row. A sum of absolute difference (SOAD) is computed for each row and stored. After each row has been loaded, the reference space is incremented to the next column. After the entire reference space has been searched, the reference block with the smallest SOAD is taken as the motion vector for the target pixel block.
