In a method, system and apparatus (100) for measuring an idle value of a Central Processing Unit (CPU) (102) in an embedded system, the CPU increments a hardware counter in accordance with clock (104) signals. The CPU also increments an idle counter during a predetermined period of time in accordance with the clock signals while an idle task is running.
