ICROPROCESSORS

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

Motorola MPC755

PowerPC Microprocessor

debug support and are fully JTAG-compliant.

Superscalar Microprocessor

MPC755 and MPC745 microprocessors are superscalar, capable

of issuing three instructions per clock cycle (two instructions

+ branch) into six independent execution units:

Two integer units

Load/store unit

Double-precision 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 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.

Cache and MMU Support

The MPC755/745 microprocessors have separate 32-Kbyte, physically-addressed instruction and data caches.

Both caches can be locked in part or whole to provide storage of critical data, key performance algorithms, or

code loops for fast response time. The MPC755 microprocessor’s dedicated L2 cache interface with on-chip L2

tags (up to 1MB) features support for direct-mapped SRAM mode, physically-mapped SRAM mode, a fast

(typically 1/2 core speed) interface to memory, instruction-only or data-only modes, and parity checking on both

L2 address and data.

MPC755/745 microprocessors contain separate memory management units (MMUs) for instructions and data,

supporting 4 Petabytes (2

) of virtual memory and 4 Gigabytes (2

) of physical memory. Both feature eight

instruction block address translation (iBAT) and eight data block address translation (dBAT) registers. Access

privileges and memory protection are controlled on block or page granularities. Large, 128-entry translation

lookaside buffers (TLBs) provide efficient physical address translation and support for virtual-memory

management on both page- and variable-sized blocks. Both hardware and software tablewalks are provided for

the TLBs.

PowerPC 755/745 CPU Summary

Flexible Bus Interface

MPC755/745 microprocessors have a

64-bit data bus with 32-bit mode and a

32-bit address bus. Support is included

for burst, split and pipelined

transactions. The interface provides

snooping for data cache coherency.

Both microprocessors maintain MEI

coherency protocol in hardware,

allowing access to system memory for

additional caching bus masters, such as

DMA devices.
