An apparatus includes a range determination module that determines a search range of TCAM content values and a search criteria module that 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 the TCAM using the search value to determine a match count. A division module creates upper and lower sub-ranges by creating upper and lower midpoint content values within the search range. The upper sub-range is between an upper content value and the upper midpoint content value and the 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. |
