| Abstract: |
In a computer system, a device for measuring power dissipation (e.g., using on-die thermal sensors) is linked to both a hardware-based thermal management solution and with a means for causing a notification event to software, so that, initially, the operating system software and/or the application software modifies its behavior in response to the notification event to reduce overall system power dissipation and the hardware-based thermal management solution is only triggered if the software solution is not effective; with both operating system and application software resuming higher-performance algorithms when power dissipation is no longer critical.

1. A computer system comprising an integrated circuit CPU, and at least one software program, in which said CPU includes sensor means responsive to a thermal property of said integrated circuit for asserting a first notification event; and said software program includes instruction means responsive to said first notification event for substituting at least one corresponding power-saving algorithm for an algorithm executed by said software program to reduce the thermal load imposed by said software program on said CPU.
