A linear systolic array based architecture for full-search block matching motion estimator
선형 시스토릭 어레이를 이용한 완전탐색 블럭정합 이동 예측기의 구조
Abstract
This paper presents a new architecture for full-search block-matching motion estimation. The architecture is based on linear systolic arrays. High speed operation is obtained by feeding reference data, search data, and control signals into the linear systolic array in a pipelined fashion. Input data are fed into the linear systolic array at a half of the processor speed, reducing the required data bandwidth to half. The proposed architecture has a good scalability with respect to the number of processors and input bandwidth when the size of reference block and search range change.
