1. xinsong1 Multimedia Extension Technology survey Xinsong Yang Electrical and Computer Engineering 734 Final Project 5/10/2002

2. xinsong2 What is it? Extension from the general purpose microprocessor without special purpose processor or dedicated hardware Extension from the general purpose microprocessor without special purpose processor or dedicated hardware Highly improve the multimedia performance Highly improve the multimedia performance SIMD extension SIMD extension

3. xinsong3 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

4. xinsong4 Implementation Intel extended MMX to IA-32 architecture Intel extended MMX to IA-32 architecture Sun enhanced VIS to UltraSPARC architecture Sun enhanced VIS to UltraSPARC architecture HP added MAX to PA-RISC architecture HP added MAX to PA-RISC architecture Motorola/IBM extended Alvetic to powerPC Motorola/IBM extended Alvetic to powerPC

5. ECE 7345 Project Goals Survey the multimedia extension technology from MMX, MAX, AltiVec, VIS Survey the multimedia extension technology from MMX, MAX, AltiVec, VIS Compare those extension and describe the common characteristic and special features Compare those extension and describe the common characteristic and special features
