Introduction

Streaming SIMD Extensions for the Intel® Architecture (IA) instruction set provides 32-bit floating point single-instruction, multiple-data (SIMD) instructions. These instructions provide a means to accelerate operations typical of 3D graphics, real-time physics, and spatial (3D) audio. This application note (AP-821) presents a method of implementing a 1/3 T software Equalizer, and includes examples of code that exploit the Streaming SIMD Extensions.
