The PPC440GP is designed using the IBM Microelectronics Blue Logic
methodology in which major
functional 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
Architecture.
Note:
IBM CoreConnect buses provide:
• 128-bit PLB interfaces up to 133.33MHz, 2.1GB/s
• 32-bit OPB interfaces up to 66.66MHz, 266MB/s
Address Maps
The PPC440GP 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 PPC440GP processor through the use of
mtdcr
and
mfdcr
instructions.
