Table 3. Processor Functions
Functional Units
The following sections briefly describe the functional units and their interaction in the system. For
more detailed information, refer to the Intel
IXC1100 Control Plane Processor Developer’s Manual.
Unless otherwise specified, the functional descriptions apply to all processors in the IXP42X
product line and IXC1100 control plane processors. Refer to
page 14
Network Processor Engines (NPEs)
The network processor engines (NPEs) are dedicated-function processors containing hardware
coprocessors integrated into the IXP42X product line and IXC1100 control plane processors. The
NPEs are used to off-load processing functions required by the Intel XScale core.
These NPEs are high-performance, hardware-multi-threaded processors with additional
local-hardware-assist functionality used to off-load highly processor-intensive functions such as
MII (MAC), CRC checking/generation, AAL 2, AES, DES, SHA-1, and MD5. All instruction code
for the NPEs are stored locally with a dedicated instruction memory bus and dedicated data
memory bus.
These NPEs support processing of the dedicated peripherals that can include:

processors, have which of these capabilities.
The NPE core is a hardware-multi-threaded processor engine that is used to accelerate functions
that are difficult to achieve high performance in a standard RISC processor. Each NPE core is a
133-MHz processor core that has self-contained instruction memory and self-contained data
memory that operate in parallel.
