  • System and method for tracing program execution within a superscalar processor
    Patent number: 6513134
    Abstract: A system and method for tracing program code within a processor having an embedded cache memory. The non-invasive tracing technique minimizes the need for trace information to be broadcast externally. The tracing technique monitors changes in instruction flow from the normal execution stream of the code. Various features, individually and in combination, provide a real-time trace-forward and trace-back capability with a minimal number of pins running at a minimal frequency relative to the processor.
