Title:
PROGRAMMABLE VARIABLE BLOCK SIZE MOTION ESTIMATION PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2014/009864
Kind Code:
A3
Abstract:
A method of performing a motion estimation search utilizing a motion estimation accelerator in a video processing system comprises a method of transmitting an original pixel data to at least one memory bank of a motion estimation engine and calculates the distortion value between the original pixel data and a predicted pixel data by a sum of absolute difference engine. Then the calculated distortion value and a plurality of predefined parameters such as cost factor are analyzed by an analyzer to obtain a minimum rate distortion cost. Further performs a cost based search in a plurality of pixel partition modes of a cost factor added pixel data and conducts an n stage motion estimation of a plurality of sub partitions in a single stretch and also performs a motion estimation process at different pipeline stages in a single pixel partition to provide a best search point of subsequent pixel partitions.
