Abstract
In one embodiment, the invention is directed to a zeroing circuit for a general purpose performance counter ('GPPC') connected to a bus carrying debug data. The zeroing circuit comprises logic for zeroing out a specified number of most significant bits ('MSBs') of a selected portion of the debug data based on a mask generated by a mask generator block. A selection control signal provided to the mask generator block is operable to be decoded to a particular mask.
