PowerPC 970 Design Objectives and Overview

Leverage architectural advantages of 64-bit POWER4

for new generation of PowerPC processor

Provide high performance general purpose processing
through advanced superscalar design with multiple,
pipelined execution units

Enhance multimedia, graphics and data movement
through hardware implementation of a SIMD processing
facility

Support the bandwidth demands of a highly superscalar
and SIMD enhanced core through a high speed
processor bus
