Abstract:
1. A motion estimator architecture for low bit rate communication comprising: previous frame storing means for storing previous search window data of a current macro block from a previous frame memory; a current frame storing means for storing current macro block data to find a motion vector in a current frame memory; a multiplexer for multiplexing the previous search window data and the current macro block data to conform to data processing thereof; data processing means having a plurality of processing elements for calculating a mean absolute error (MAE) of the motion vector based on the previous search window data and the current macro block data transmitted from the multiplexer; comparing means for comparatively detecting the MAE of each motion vector from the data processing means to detect a motion vector having a least MAE; and state control means for controlling data flow between the above components, wherein the motion estimator estimates the motion vector selecting one of a full search method and an interlace search method depending on image characteristics and bit rate.
