On Architecture of Multi-core Packet Processing System
Wu Zhang · Microcomputer applications · 2010
According to the characteristics of packet processing and multi-core processor,a detailed analysis on multi-core packet processing system was presented,witch took both overhead of communication between cores and stall caused by cold cache into account.An experiment on a multi-core network processor platform was carried out to verify the analysis.Both of the results shows that it’s possible for a hybrid architecture to over perform a completely paralleled architecture,only if the processing resources allocated to each stage are balanced well.Further more,some critical problem must be over come in the design space of hybrid architecture were presented,as well as some basic design principles.
