• Embedded RISC Executive Processor
• Integrated 32bit 33/66MHz PCI bus interface
Block Diagram
The C-3eTM NP, has an architecture specifically designed for networking applications. The
following sections describe each component of the C-3e NP.
The main components of the C-3e NP are:
• Channel Processors
• Executive Processor
• Fabric Processor
• Buffer Management Unit
• Table Lookup Unit
• Queue Management Unit
The C-3e NP conforms with both SONET and SDH. Therefore, OC-3(STS-3/STM-1), and
OC-12 (STS-12/STM-4).
Figure 1 shows a block diagram of the C-3e NP, including its potential external interfaces.
For more information about the architecture of the C-3e NP, see the C-5e/C-3e Network
Processor Architecture Guide (part number C5EC3EARCH-RM/D).
