PowerPC 750 microprocessor. PowerPC 750/740 microprocessors contain separate memory management units
(MMUs) for instructions and data, supporting 4 Petabytes (252) of virtual memory and 4 Gigabytes (232) of physical
memory. 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 demand virtual-
memory management on both page- and variable-sized blocks.
Flexible Bus Interface
PowerPC 750/740 microprocessors have a 64-bit data bus 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.
