ABSTRACT:
A method may include performing an N bit-at-a-time matching operation for a first N bits in an encoded input stream of bits using a lookup table. The matching operation may obtain a first address in the table, and N may be an integer greater than one. The method may also include obtaining a second address in the table based on a mask and a jump address that are associated with the first address and a second number of bits in the encoded input stream. An index value may be output based on the second address in the table.
