POWER Performance Optimized With Enhanced RISC architecture
(IBM)
PowerPC™ The trademark used to describe the Performance Optimized
With Enhanced RISC microprocessor architecture for
Personal Computers developed by the IBM Corporation.
PowerPC is superscalar, which means it can handle more
than one instruction per clock cycle. Instructions can be sent
simultaneously to three types of independent execution
units (branch units, fixed-point units, and floating-point
units), where they can execute concurrently, but finish out
of order. PowerPC is used by Motorola, Inc. under license
from IBM.
PowerPC 601™ The first implementation of the PowerPC family of
microprocessors. This CPU incorporates a memory
management unit with a 256-entry buffer and a 32KB
