Abstract

In this paper, a novel pipelined algorithm is applied in the hardware implementation of Smith-Waterman algorithm. The proposed algorithm can cut down the computation time from O(m+n) to O(m+n/J), where J is the pipeline level, m and n are the lengths of the query sequence and subject sequence respectively. It's obvious that if the length of subject sequence is much larger than the query sequence, i.e., nm, the computation of scanning protein sequences will be speeded up by a factor of J.
