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
52
) of virtual memory and 4 Gigabytes (2
32
) 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.
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.
