PPC440GX Functional Block Diagram
The PPC440GX is designed using the IBM
blocks are integrated together to create an application-specific product (ASIC). This approach provides a
consistent way to create complex ASICs using IBM CoreConnect Bus
Note: IBM CoreConnect buses provide:
Address Maps
The PPC440GX 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 address map is for Device Configuration Registers (DCRs). The DCRs are accessed by software running
on the PPC440GX processor through the use of mtdcr and mfdcr instructions.
