Network processor system on chip with bridge coupling protocol converting multiprocessor macro core local bus to peripheral interfaces coupled system bus

摘要

A network processor includes a system-onchip (SoC) macro core and functions as a single chip protocol converter that receives packets generating according to a first protocol type and processes the packets to implement protocol conversion and generates converted packets of a second protocol type for output thereof, the process of protocol conversion being performed entirely within the SoC macro core. The process of protocol conversion contained within the SoC macro core does not require the processing resources of a host system. The system-on chip macro core includes a bridge device for coupling a local bus in the protocol converting multiprocessor SoC macro core local bus to peripheral interfaces coupled to a system bus.
