Abstract
In accordance with methods and systems consistent with the present invention, an improved processor performance instrumentation system is provided that allows a software tester to measure more performance indicators than there are hardware counters during a single execution of a tested program. The improved processor performance instrumentation system accomplishes this by “multiplexing” performance indicators while executing the tested program. In effect, methods and systems consistent with the present invention extend the abilities of the limited number of hardware counters to allow them to measure a number of performance indicators otherwise not allowed during one execution of the tested program.
