V 4373 System Controller
RC
Data Sheet
October 1997
1.0
1.1
Introduction
The V
RC
4373
TM
system controller is a software-configurable chip that directly interfaces
the V
R
4300
TM
CPU and PCI bus without external logic or buffering, and also interfaces
memory (SDRAM, EDO, fast-page DRAM, and flash boot ROM) with minimal buffer-
ing. From the viewpoint of the V
R
4300 CPU, the V
RC
4373 acts as a memory controller,
DMA controller, and PCI bridge. From the viewpoint of PCI agents, the V
RC
4373 acts
as either a PCI bus master or a PCI bus target. Alternatively, the V
RC
4373 may be
located on a PCI bus add-on board.
