摘要
This paper presents an efficient architecture to implement low power variable block size motion estimation (VBSME) using full search. Power reduction is achieved by performing the search in two steps: low pixel resolution and full pixel resolution. We analysed the computation and memory units needed to support these two search modes. The proposed architecture reduces the total energy consumption by 50% with 6% additional area compared to the conventional architecture.
