VRC4375 System Controller
August 2000
The VRC4375TM system controller is a software-configurable chip that interfaces directly with an NEC VR43xxTM 64-bit MIPS RISC CPU and PCI bus without external logic or buffering. The system controller also interfaces with memory (SDRAM, EDO, fast-page DRAM, and flash/boot ROM) with minimal to no buffering. The memory bus can also interface with SRAM and general-purpose I/O devices. As an interface with the VR43xx CPU, the VRC4375 acts as a memory controller, DMA controller, and PCI bridge. As an interface with PCI agents, the VRC4375 acts as either a PCI bus master or a PCI bus...
