ABSTRACT

An efficient method for reducing power consumption in pipelined deep packet inspection systems isproposed. It is based on the observation that the number of memory accesses is dominant for the powerconsumption and the number of accesses drops drastically as the input goes through stages of thepipelined AC-DFA. A DPI system is implemented where the operating frequency of the stages that are notfrequently used in the pipeline is reduced to eliminate the waste of power consumption. The powerconsumption of the proposed DPI system is measured upon various input character set and up to 25% of reduction of total power consumption is obtained, compared to those of the recent DPI systems. Themethod can be easily applied to other pipelined architecture and string searching applications.
