An efficient, low-cost I/O subsystem for network processors
D.N. Pnevinatikatos, L. Sourdis, K. Vlachos · IEEE Design & Test of Computers · 2003
An efficient I/O subsystem enables cost-effective network processing. To improve high-speed data transfer, the I/O subsystem sends data directly into the processing core's register file. An implementation of this subsystem in a single-chip network processor , the Pro/sup 3/, can sustain advanced inspection firewall processing of 2.5-Gbps TCP traffic.
