PROGRAM TRACE MESSAGE GENERATION FOR PAGE CROSSING EVENTS FOR DEBUG

摘要

A data processing system has a trace message filtering circuit. A method includes: receiving a current page address corresponding to a current instruction in a sequence of instructions; determining that the current page address is for a different page of memory than a previous page address corresponding to a previous instruction in the sequence of instructions; comparing the current page address with a plurality of page addresses stored in a message filtering circuit; and when the current page address is determined to be different than any of the plurality of page addresses, storing the current page address in the message filtering circuit.
