MPC755 and MPC745 PowerPC microprocessors are high-performance, low-power, 32-bit implementations of

the PowerPC Reduced Instruction Set Computer (RISC) architecture, specially enhanced for embedded applications.

MPC755 and MPC745 microprocessors differ only in that the MPC755 features an enhanced, dedicated L2 cache

interface with on-chip L2 tags. The MPC755 is a drop-in replacement for the award winning PowerPC 750™

microprocessor and is footprint and user software code compatible with the MPC7400 microprocessor with AltiVec

™ technology. The MPC745 is a drop-in replacement for the PowerPC 740™ microprocessor and is also footprint

and user software code compatible with the PowerPC 603e™

microprocessor. MPC755/745 microprocessors provide on-chip

debug support and are fully JTAG-compliant.

PowerPC Microprocessor

Superscalar Microprocessor

MPC755 and MPC745 microprocessors are superscalar, capable

of issuing three instructions per clock cycle (two instructions

+ branch) into six independent execution units:

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 for MPC755 and MPC745 systems.

Power Management

The MPC755 and MPC745 microprocessors feature a

low-power 2.0-volt design with three power-saving user-

programmable modes — doze, nap and sleep — which

progressively reduce the power drawn by the processor.

These low-power microprocessors offer dynamic power

management to selectively activate functional units as they

are needed by the executing instructions. Both

microprocessors also provide a thermal assist unit and

instruction cache throttling for software-controllable

thermal management.
