基于MPC8321的路由器的设计与实现

his paper provides a design method of a router with switch function, though formulatting the project, selecting the chip, designing schematic, designing PCB, use MPC8321 as CPU, use BCM5324 as switch chip, design a router combined with a layer 2 switch.The CPU of this router provides 2 10/100M ethernet interfaces as up data interface,and 2 UART interfaces.The BCM5324 provides 24 10/100M ethernet interfaces as down data interface.This system also provides a PCI backplate slot and a VM slot, using to connected with other equipment that have a PCI backplate slot or connected with a CE1 or a synchronization interfaces that can communicate with other net.
