The PowerPC 603e microprocessor also uses dynamic power management to selectively activate functional units as they are needed by the executing instructions. Unused functional units enter a low-power state automatically without affecting performance, software execution, or external hardware. Access privileges and memory protection are controlled on block or page granularities.
Support is included for burst, split and pipelined transactions.
The interface provides snooping for data cache coherency. The PowerPC 603e microprocessor maintains MEI coherency protocol in hardware, allowing access to system memory for additional caching bus masters, such as DMA devices. Inc. All rights reserved.
