A Generalized Frame-Level FSBM FLSA Architecture

Abstract

Block-based motion estimation plays important roles in video applications such as video compression to detect movements as well as remove temporal redundancies between successive frames. Full-search block-matching (FSBM) is the preferred algorithm for accurate motion estimation. Frame-level pipelined systolic array (FLSA) FSBM architectures have advantages over block-level pipelined architectures in their simpler control and reduced number of memory accesses. In this paper, a frame-level pipelined FSBM motion estimation architecture using array processor for any square, N×N, block size is presented in full detail.
