The 603R is a low-power implementation of the PowerPC microprocessor family of Reduced
Instruction Set Computing (RISC) microprocessors. The 603R implements the 32-bit portion of
the PowerPC architecture, which provides 32-bit effective addresses, integer data types of 8, 16
and 32 bits, and floating-point data types of 32 and 64 bits. For 64-bit PowerPC microproces-
sors, the PowerPC architecture provides 64-bit integer data types, 64-bit addressing, and other
features required to complete the 64-bit architecture.
The 603R provides four software controllable power-saving modes. Three of the modes (nap,
doze, and sleep) are static in nature, and progressively reduce the amount of power dissipated
by the processor. The fourth is a dynamic power management mode that causes the functional
units in the 603R to automatically enter a low-power mode when the functional units are idle
without affecting operational performance, software execution, or any external hardware.
The 603R is a superscalar processor capable of issuing and retiring as many as three instruc-
tions per clock. Instructions can be executed in any order for increased performance, but, the
603R makes completion appear sequential.
The 603e integrates five execution units:
• an Integer Unit (IU)
• a Floating-point Unit (FPU)
• a Branch Processing Unit (BPU)
