Abstract

A RAM_HIME used for integer pixel motion estimation by an IME stores integer pixel luminance data from a SDRAM while satisfying the conditions that improve efficiency in reading an extracted rectangular area. A RAM_HSME used for motion estimation of quarter-pixel accuracy by a SME stores partial quarter-pixel luminance data while satisfying the conditions that improve efficiency in obtaining a rectangular area after calculation by calculation. A RAM_HMEC used for chrominance data generation of quarter-pixel accuracy by a QPG stores integer pixel chrominance data from the SDRAM while satisfying the conditions that improve efficiency in obtaining rectangular areas after calculation by calculation.
