Abstract
An apparatus for digital filtering of sequences of data units, such as sequences of bytes. The apparatus uses parallel application of more than one filter and stores the results of applying all filters to a whole sequence of data units. The apparatus involves the interaction of random access memories. Hence, filters are programmable. In addition, individual data units in a sequence may be trapped for comparison solely as a function of their ordinal position in the sequence.
