We propose an FPGA design for the relevancycomputation part of a high-throughput real-time search application. The application matches terms in a stream ofdocuments against a static profile, held in off-chip memory. We present a mathematical analysis of the throughput ofthe application and apply it to the problem of scaling theBloom filter used to discard nonmatches.
