440EPx – PPC440EPx Embedded Processor
Block Diagram
Figure 2. PPC440EPx Functional Block Diagram
The PPC440EPx is a system on a chip (SOC) using IBM CoreConnect Bus
Address Maps
The PPC440EPx incorporates two address maps. The first is a fixed processor System Memory Address Map.
This address map defines the possible contents of various address regions which the processor can access. The
second is the DCR Address Map for Device Configuration Registers (DCRs). The DCRs are accessed by software
running on the PPC440EPx processor through the use of mtdcr and mfdcr instructions.
