Abstract: The dilatability increase of network scale, the rapidity enhancement need of network bandwidth by users, the emergence in endlessly of vary kinds of new services, the technical need of intellectualized management and upgrading applications speed up the naissance of network processor. A new generation of network equipment architecture based on the kernel of network processor has been formed. This paper introduces simply the definition and functions of NP, the architecture and characteristics of NP, the main differences between NP and general CPU are analyzed, and the architecture of micro-engine which is the main logic block of NP is described. Then some keystones how to design micro-engine are given.
Key words:
Network processor(NP),
Micro-engine,
Microcode,
Multithread,
