Abstract:
1. A high-speed motion estimation apparatus, comprising: a current region memory receiving pixel data of a current region from an external frame memory to store the pixel data; an integer-times motion estimation unit storing pixel data of an estimation region which are read from the frame memory in a sharable multiple input/output bank type, and predicting an integer-times motion vector by using the pixel data of the current region and the pixel data of the estimation region; and a decimal-times motion estimation unit reading the pixel data of the estimation region from the integer-times motion estimation unit, and predicting a decimal-times motion vector by using the read pixel data of the estimation region and the integer-times motion vector predicted by the integer-times motion estimation unit, when an estimation region sharable signal is received from the integer-times motion estimation unit.
