Abstract
This paper presents an architectural enhancement to reduce the power consumption of the full-search block-matching (FSBM) motion estimation. Our approach is based on eliminating unnecessary computation using conservative approximation. Augmenting the estimation technique to a conventional systolic-architecture-based VLSI motion estimation reduces the power consumption by a factor of 2, while still preserving the optimal solution and the throughput. A register-transfer level implementation as well as simulation results on benchmark video clips are presented.
