Absolute-Difference Motion Estimation for Intel® Pentium® 4 Processors

Introduction

The media extensions to the Intel Architecture (IA) instruction set include single-instruction, multiple-data (SIMD) instructions. Streaming SIMD Extensions 2 (SSE2) instructions extend SIMD for the Intel NetBurst® microarchitecture with 144 new instructions. This paper describes an SSE2 implementation to calculate the absolute difference between two 16x16 blocks of pixels. This paper also compares the performance gains of that solution to non-SSE2 implementations. This SSE2 solution can be an integral part of a motion-estimation kernel.

    Introduction

    This guide discusses the Intel® Pentium® 4 processor with Hyper-Threading Technology (code named Prescott).

    Prescott is the code name for a new generation of IA32 processors. The technology incorporates an enhanced Intel® NetBurst® microarchitecture. Other features include:

    • Support for Hyper-Threading (HT) Technology
    • Prescott New Instructions (PNI)
    • Deeper pipelining to enable higher frequency
    • A High-speed System Bus

    Далёкий 1988й год был полон удивительных событий. В этом году увидел свет 4й альбом группы Metallica «...And justice for all», а СССР запустил в свой первый и единственный полёт многоразовый космический корабль «Буран».
