Title: DIAGNOSTIC DATA CAPTURE
Abstract:
Statistical sampling of diagnostic data within an apparatus for processing data 2 is performed based upon sample interval monitoring and address monitoring. A program instruction has its diagnostic data stored when it meets a sample interval criteria and an address match criteria. The address match may correspond to an instruction address of the program instruction or a target address to be read or written by the program instruction.
