Abstract
A data stream filter includes a first memory bank storing a pattern field, and a second memory bank storing an enable field. A comparator compares units of an input data stream with identically sized units of the pattern field according to corresponding units of the enable field. An input controller, coupled to the comparator and second memory bank, writes matching units of the input data stream over the corresponding units of the pattern field, and an output controller, coupled to the comparator and the second memory bank outputs the content of the second memory bank when all units of the pattern field are matched.
