NPE405H EMBEDDED CONTROLLER FUNCTIONAL BLOCK DIAGRAM
Figure 1. NPe405H Embedded Controller Functional Block Diagram
The NPe405H 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.
