UMHexagonS Based Motion Estimation Architecture Comparison

Abstract — This paper is a presentation of the existing design and review of hardware for UMHexagonS based motion estimation for H.264/AVC video compression. Four existing motion estimation architectures that implement UMHexagonS are presented, analysed, and compared to show the area needing future improvements. The presented architectures are also compared against our proposed architecture. The results are compared in terms of gate count and throughput with emphasis on throughput as it shows the speed of the architecture. The proposed architecture gives a promising result compared with some of the reviewed architecture. It shows an improvement of 91 % compared to the full search architecture and 20 % compared to a basic UMHexagonS architecture
