Page 2 Industrial Technology Research Institute Computer & Communication Research Laboratories Network Processors Markets +A high-layer packet-analysis and forwarding function currently served by ASICs +A control function for handling multiple routing and switching channels, usually served by a RISC device such as the 960 or StrongARM +An application processor function for specialized duties such as quality-of-service (QoS) bit assignment and virtual-private- network tunnel creation. +In some cases, the network processor offloads critical instructions from the host processor in a system, thereby improving throughput. In other cases, these new processors can replace the host CPU.
