System And Method For Throttling A Clock Speed By Comparing A Power Value With A Predetermined Power Value Wherein The Predetermined Power Value Is Based On An Increasing Rate Of A Parameter

Summary

The present invention provides an apparatus and method for controlling power and clock speed of an electronic system. The present invention detects a voltage signal and a current signal as the electronic system is operating, and obtains a power value. The present invention decides whether the power value is greater than a predetermined power value. When the power value is greater than the predetermined power value, the clock speed of the electronic system is throttled in accordance with an on-off rate.

Technology Application

Processor

Detailed Technology Description

A method for controlling a clock speed of an electronic system, said method comprising the steps of:
(A) detecting and outputting a voltage signal and a current signal as said electronic system is operating;
(B) calculating a power value in response to said voltage signal and said current signal;
(C) determining whether said power value is greater than a predetermined power value; and
(D) throttling said clock speed in accordance with an on-off rate when said power value is greater than said predetermined power value, said on-off rate being chosen according to an increasing rate of a parameter on which said predetermined power value is based.
