Description

The CPC710 IBM PCI Bridge and Memory

Controller is a highly integrated host bridge device

that interfaces PowerPC 60x buses to SDRAM-

based system memory and also provides two PCI

interfaces. It supports up to four processors with

pipelining for up to six outstanding transaction

requests.

The memory controller supports SDRAM, allowing

the memory to burst data on most bus cycles at

100MHz or 133MHz.

For system designs requiring high I/O bandwidth,

there are two PCI host bus bridges. One bridge

supports a standard 32-bit, 33MHz PCI bus, while

the other supports 64 bits at up to 66MHz for

graphics and high speed communications.

An internal DMA controller allows high speed data

transfer between Memory and I/O. Store-gathering

enhances the CPU-to-I/O performance.
