Abstract: A high-speed motion estimation method for estimating a motion of a picture at high speed in a high-speed motion estimation apparatus including an integer-times motion estimation unit and a decimal-times motion estimation unit. The integer-times motion estimation unit (1) receives pixel data of a picture for estimation of motion from an external frame memory, (2) stores pixel data of a current region in a current macroblock storage where multiple inputs/outputs are made, (3) stores pixel data of an estimation region in an estimation region macroblock storage of a sharable multiple input/output bank type, and (4) predicts an integer-times motion vector using both stored pixel data. The decimal-times motion estimation unit reads the pixel data of the estimation region from the estimation region macroblock storage which is sharable, and predicts a decimal-times motion vector using the read pixel data of the estimation region and the integer-times motion vector.
