Abstract: A system and method are disclosed for inexact search acceleration using reference data. A representative system includes one or more memory circuits storing a plurality of queries and a FM-index of the reference data; and one or more FPGAs configured to select a query; select a substring of the selected query; read a section of the FM-index and calculate a plurality of suffix array intervals for the sub string with a corresponding plurality of prepended characters in a first or next position; read a first or next character in the first or next position of the query and select a suffix array interval for the read first character; determine whether the suffix array interval is valid and whether a beginning of the query has been reached; returning a first search result when the suffix array interval is valid and the beginning of the query has been reached; and returning a second search result that no match of the query with the reference data was found when the suffix array interval is not valid.
