Abstract
A match circuit connected to a bus carrying data is described. In one embodiment, the match circuit includes logic for activating a decoded_match signal, the logic for activating a decoded match signal comprising logic for decoding a sum field comprising a selected portion of the data into a decoded_sum signal, wherein an active bit of the decoded_sum field corresponds to a value of the sum field; and logic for comparing the decoded_sum signal with a mask signal and outputting a binary bit comprising a decoded_match signal indicative of whether the decoded_sum signal and the mask signal match.
