ABSTRACT:
In a computer system having a cpu, a device for dynamic cpu clock adjustment. The device is comprised of a clock pulse generator for generating a clock frequency. The clock frequency is coupled to the cpu and is used by the cpu to synchronize and pace its internal operations. The clock frequency generated by the generator is variable over a range. A controller is coupled to the clock pulse generator, for adjusting the clock frequency from the clock pulse generator over the range. The controller interfaces with the computer system through an interface coupled to the controller. Through the interface, the controller communicates with the computer system or cpu and determines a load placed on the cpu. The controller adjusts the clock frequency generated by the clock pulse generator such that the clock frequency increases when the load on the cpu increases and the clock frequency decreases when the load on the cpu decreases, dynamically adjusting the clock frequency in response to the load on the cpu.
