processors
are difficult for a processor to implement. The type of functions implemented by the co-
processors are serialization/de-serialization, CRC checking/generation, DES/3DES,
AES, SHA-1, MD-5, and HDLC bit-stuffing/de-stuffing. These coprocessors are
implemented in hardware, therefore allowing the coprocessors and the Network
Processor Engine core to operate in parallel.
The combined forces of the hardware multi-threading, local code store, independent
instruction memory, independent data memory, and parallel processing allows the Intel
XScale processor to be utilized for application purposes. The multi-processing capability
of the peripheral interface functions allows unparalleled performance to be achieved by
the application running on the Intel XScale processor.
