Multimedia Extension Technology survey

This project explores multimedia extension technologies that enhance general-purpose microprocessors through SIMD (Single Instruction, Multiple Data) operations. It focuses on specialized operations aimed at improving multimedia performance, such as data reorganization (unpacking, shuffling, shifting) and advanced load/store instructions. The report examines various implementations, including Intel's extended MMX, Sun's VIS for UltraSPARC, HP's MAX for PA-RISC, and Motorola/IBM's AltiVec for PowerPC. The goal is to compare these extensions, highlighting their common characteristics and unique features in multimedia applications.

  1. Multimedia Extension Technology survey Xinsong Yang Electrical and Computer Engineering 734 Final Project 5/10/2002 xinsong

  2. What is it? • Extension from the general purpose microprocessor without special purpose processor or dedicated hardware • Highly improve the multimedia performance • SIMD extension xinsong

  3. General characteristic • Parallel execution using packed data in one instruction(arithmetic, logical) • A set of specialized operations for media applications. • Reorganization of operands in a SIMD format – unpack, shuffle, shift, permute, etc. • Data prefetch and streaming load/store instructions xinsong

  4. Implementation • Intel extended MMX to IA-32 architecture • Sun enhanced VIS to UltraSPARC architecture • HP added MAX to PA-RISC architecture • Motorola/IBM extended Alvetic to powerPC xinsong

  5. Project Goals • Survey the multimedia extension technology from MMX, MAX, AltiVec, VIS • Compare those extension and describe the common characteristic and special features ECE 734
