NPe405H Embedded Controller Functional Block Diagram
The NPe405H is designed using the IBM Microelectronics Blue Logic
functional blocks are integrated to create an application-specific ASIC product. This approach provides a
consistent way to generate complex ASICs using IBM CoreConnect
TM
methodology in which major
TM
Bus Architecture.
Note:
IBM CoreConnect busses provide:
64-bit PLB interfaces up to 133MHz
32-bit OPB interfaces up to 66MHz
Address Map Support
The NPe405H incorporates two simple and separate address maps. The first is a fixed processor address
map that serves the PowerPC family of processors. 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 (DCR). This address map is accessed by software running on the NPe405H
processor through the use of
mtdcr
and
mfdcr
commands.
