Contextual Info: VRC5074 System Controller June 1998 Data Sheet 1.0 Introduction 1.1 The VRC5074 System Controller is a software-configurable chip that directly connects the V R5000 CPU to SDRAM memory, a PCI Bus, and a Local Bus, without external logic or buffering. From the CPU’s viewpoint, the controller acts as a memory controller, DMA controller, PCI-Bus host bridge, and Local-Bus host bridge. From the viewpoint of PCI agents, the controller acts as master and target on the PCI Bus. The
