Abstract

In one embodiment, the invention is directed to a match circuit for implementation in a general purpose performance counter (“GPPC”) connected to a bus carrying debug data. The match circuit comprises logic for activating a match signal when a selected N-bit portion of the debug data matches an N-bit threshold for all bits selected by an N-bit match mask (“mmask”).
