Figure 1-3. Embedded System Using an MPC8240 as a Peripheral Processor
Figure 1-4 shows the MPC8240 as a distributed I/O processing device. The PCI-to-PCI
bridge shown could be of the PCI type 0 variety. The MPC8240 would not be part of the
system configuration map. This configuration is useful in applications such as RAID
controllers, where the I/O devices shown are SCSI controllers, or multi-port network
controllers where the devices shown are Ethernet controllers.
