Abstract:
A method includes receiving input data comprising a plurality of bits and processing an access control list into an ESOP expression comprising a plurality of product terms. The method also includes storing a plurality of bits associated with the plurality of product terms in a TCAM comprising a plurality of rows and comparing the plurality of bits associated with the input data to the plurality of bits associated with the product terms stored in each row of the plurality of rows, such that each row of the TCAM outputs a plurality of signals, such that each of the plurality of signals indicate a match or no match for each bit stored in the selected row. The method includes receiving the plurality of signals from the plurality of rows by an ESOP evaluator and outputting an address associated with a selected row from the plurality of rows of the TCAM.
