  • External trace synchronization via periodic sampling
    Patent number: 8185879
    Abstract: A method for tracing a multi-tasking embedded pipelined processor includes executing compiled code including trace controls. Tracing is initiated when the execution of the compiled code is initiated. Tracing is stopped when execution of the compiled code is completed. A trace record is formed during tracing. The trace record includes a processor mode indication, application space identity value and an instruction architecture set mode indication.
