Abstract
A range determination module determines a search range of TCAM content values and a search criteria module creates a TCAM search value from a search range by combining common higher order bits with don't care lower order bits that change within the search range. A match module searches TCAM using the search value to determine a match count. A division module creates upper/lower sub-ranges by creating upper/lower midpoint content values within the search range. Upper sub-range is between an upper content value and the upper midpoint content value and lower sub-range is between the lower midpoint content value and a lower content value. The upper midpoint content value includes changing a most significant don't care bit to a 1 and remaining don't care bits to 0. The lower midpoint content value includes changing a most significant don't care bit to 0 and remaining don't care bits to 1.
