Abstract
Methods and systems for a reconfigurable pattern filtering engine may include assembling a hardware filter from a plurality of minimum length hardware filters. A length of the assembled hardware filter may vary in multiples of a length of one of the minimum length hardware filters. The assembled hardware filter and the minimum length hardware filters may be integrated within a single chip. Specific messages in the data stream may be filtered using the assembled hardware filter. The assembled hardware filter may use at least one filter coefficient, an inclusion mask, and an exclusion mask to filter messages. At least a portion of the filtered messages may be stored in memory via direct memory access transfers.
