Motion Estimation Algorithms Using Streaming SIMD Extensions 3


Introduction

The Streaming SIMD Extensions 3 (SSE3) for IA-32 Intel Architecture accelerates performance of Streaming SIMD Extensions 2 (SSE2) technology, Streaming SIMD Extensions (SSE) technology, and scientific applications over the current Intel® Pentium® 4 processor generation. SSE3 introduces new instructions that significantly improve complex arithmetic evaluation, evaluations of quantities like dot products, conversion to integer for applications using x87-FP code, and 128-bit unaligned memory accesses. In addition, SSE3 has added support for better synchronization between multiple agents over the current Pentium 4 processor generation.
