Abstract: A system for interpolating half-pels from a pixel array stores pixel data for each pixel in one of a plurality of different memory areas based on a location of the pixel within the pixel array, and determines a specific address in each one of the plurality of memory areas based on a target pixel in the pixel array. The system determines each specific address based on a location of the target pixel in the pixel array. The system also reads, from each the plurality of memory areas, pixel data from determined specific addresses and determines a value of at least one half-pel for the target pixel based on the read pixel data.
