Abstract

A combinational encoder (100) according to one embodiment is disclosed. The combinational encoder (100) can be used with an address encoder (300) to provide a compact priority encoder. The combinational encoder (300) receives a number of input signals (MATCH_IN0-MATCH_IN3) and provides a like number of output signals (MATCH_OUT0-MATCH_OUT3). Unlike a conventional priority encoder, which activates a single output signal in response to various input signal combinations, the combinational encoder (100) provides multiple active output signals in response to particular combinations of input signals. When applied to an appropriate address encoder (300), the multiple active output signals generate address values reflecting the desired priority of the input signals.
