Aptiva - 2159 S80 and S90 Unique Features (Overview)
Applicable to: World-Wide
This document covers MMX Technology.
MMX Technology:
The dominant change in MMX technology between the 2159 S80, S90, R18, R19 and most later model machines is the change to the MMX Processor.
The MMX technology is designed to accelerate multimedia and communications software.
The highlights of the technology are:
SIMD (Single Instruction, Multiple Data) techniques to processing.
57 new instructions
Eight 64-bit wide MMX registers
Four new data types
What it does for you:
MMX is the first major enhancement to the 80xxx chip since the i386 (TM) processor. This technology is oriented toward highly - parallel processing. The Basis for the MMX technology is a technique called Single Instruction, Multiple Data or SIMD. This allows many pieces of information to be processed with a single instruction, providing parallelism and subsequently greatly increasing performance. These SIMD enhancements are most valuable when the applications used are multi-media and communications based apps, that are written for the MMX processor.
Compatibility:
MMX processors are compatible with all existing software. However, it is possible that software manufacturers will begin writing code specifically designed for the registers built onto the CPU.
