NPe405L Embedded Controller Functional Block Diagram

The NPe405L is designed using the IBM Microelectronics Blue Logic

 methodology in which major functional

blocks are integrated to create an application-specific ASIC product. This approach provides a consistent way

to generate complex ASICs using IBM CoreConnect

 Bus Architecture.

Address Map Support

The NPe405L incorporates two 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

(DCRs). The DCRs are accessed by software running on the NPe405L processor through the use of mtdcr

and mfdcr commands.
