The Motorola MPC603r microprocessor is a low-power implementation of the PowerPC Reduced Instruction

Set Computer (RISC) architecture. The MPC603r microprocessor offers workstation-level performance packed

into a low-power, low-cost design ideal for desktop computers, notebooks and battery-powered systems,

as well as printer and imaging equipment, telecommunications systems, networking and communications infra-

structure, industrial controls, and home entertainment and educational devices. Industrial-grade, extended

temperature MPC603r microprocessors are available for harsh operating environments. The MPC603r micro-

processor is software- and bus-compatible with the MPC7xx and MPC74xx microprocessor families.

S u p e rs c a la r M ic ro p ro c e s s o r

The MPC603r microprocessor is a superscalar design

capable of issuing three instructions per clock cycle into five

independent execution units, including:

■

Integer unit

■

Load/Store unit

■

Floating-point unit

■

System register unit

■

Branch processing unit

The ability to execute multiple instructions in parallel, to pipeline

instructions, and the use of simple instructions with rapid

execution times yields maximum efficiency and throughput.

power-saving modes—doze, nap and sleep. These

user-programmable modes progressively reduce the

power drawn by the processor. The microprocessor

also uses dynamic power management to selectively

activate functional units as they are needed by the exe-

cuting instructions. Unused functional units enter a

low-power state automatically without affecting per-

formance, software execution, or external hardware.
