1. one kind for maintaining the system (10) of performance of integrated circuit (70), and this system comprises:

  • Operating power limit evaluator (18,32), it determines the function of the operating power limit as at least one performance factor relevant with the variation of performance that affects integrated circuit (70);

    WithPower management system (12,72), its real power according to the operating power limit and integrated circuit (70) changes the power of integrated circuit (70) to maintain constant performance,Wherein the operating power limit is dynamically adjusted to lower than the maximum allowable power limit of specifying,Wherein at least one performance factor is at least one the function of parameter in inherent feature, the manufacture variation of integrated circuit (70) and the service condition of integrated circuit (70) based on integrated circuit (70).
