Abstract
A system and method for performing similarity searching is disclosed. This includes a programmable logic device configured to include a pipeline that comprises a matching stage, the matching stage being configured to receive a data stream comprising a plurality of possible matches between a plurality of data strings and a plurality of substrings of a query string. The pipeline may further include an ungapped extension prefilter stage located downstream from the matching stage, the prefilter stage being configured to shift through pattern matches between the data strings and the plurality of substrings of a query string and provide a score so that only pattern matches that exceed a user defined score will pass downstream from the prefilter stage. The matching stage may include at least one Bloom filter.
