MPC8540 Overview
OCeaN switch fabric
— Four-port crossbar packet switch
— Reorders packets from a source based on priorities
— Reorders packets to bypass blocked packets
— Implements starvation avoidance algorithms
— Supports packets with payloads of up to 256 bytes
Integrated DMA controller
— Four-channel controller
— All channels accessible by both the local and remote masters
— Extended DMA functions (advanced chaining and striding capability)
— Support for scatter and gather transfers
— Misaligned transfer capability
— Interrupt on completed segment, link, list, and error
— Supports transfers to or from any local memory or I/O port
— Selectable hardware-enforced coherency (snoop/no-snoop)
— Ability to start and flow control each DMA channel from external 3-pin interface
— Ability to launch DMA from single write transaction
PCI/PCI-X controller
— PCI 2.2 and PCI-X 1.0 compatible
— 64- or 32-bit PCI port supports at 16 to 66 MHz
— 64-bit PCI-X support up to 133 MHz
— Host and agent mode support
— 64-bit dual address cycle (DAC) support
— PCI-X supports multiple split transactions
— Supports PCI-to-memory and memory-to-PCI streaming
— Memory prefetching of PCI read accesses
— Supports posting of processor-to-PCI and PCI-to-memory writes
— PCI 3.3-V compatible
— Selectable hardware-enforced coherency
Power management
— Fully static 1.2-V CMOS design with 3.3- and 2.5-V I/O
— Supports power saving modes: doze, nap, and sleep
— Employs dynamic power management, which automatically minimizes power consumption of blocks
when they are idle
System performance monitor
— Supports eight 32-bit counters that count the occurrence of selected events
— Ability to count up to 512 counter-specific events
— Supports 64 reference events that can be counted on any of the 8 counters
— Supports duration and quantity threshold counting
