High Throughput, Scalable VLSI Architecture for Block Matching Motion Estimation

Abstract

A VLSI architecture for the block matching motion estimation is described in this paper. The proposed architecture achieves 100% PE utilization and alleviates I/O bottleneck problem using small amount of distributed on-chip image memory. The number of processing elements is scalable according to the degree of parallel processing and throughput requirement. The overall computations are performed in pipelined manner and the data fill time for contiguous block is eliminated to increase throughput. The VLSI system implementation methodologies and the layouts are also described. Finally, the performances are evaluated and the advantages are outlined, compared to other architectures.
