Problems solved by technology

Unfortunately, as processor speed increases, the power consumed by the processor also tends to increase
Historically, the power consumed by a processor has been limited by two factors
First, as power consumption increases, the processor tends to get hotter, causing thermal problems
Second, as power consumption increases, the battery life of mobile computer systems shortens, making the system less attractive to consumers
If these precautions are not taken, the processor can be destroyed by its own heat

Embodiment Construction

[0049] Computer system power consumption is now rapidly approaching the point where the power required to operate the system is no longer reliably supplied to the system. This is due firstly to the fact that one or more processors contained in a system plugged into a power outlet may, during periods of excessive activity, consume more power than the power outlet can supply. In this case, the fuses or circuit breakers protecting the power outlets may open (or blow) during normal operation of the system.

[0050] According to one embodiment of the invention, power consumed by at least a portion of a computer system is monitored by measuring a parameter approximately proportional to the power consumed, such as voltage, current, or duty cycle of a switching signal in a power supply . These measurements are provided to the power controller. The monitored portion of the computer system may include one or more processors of the computer system, in addition to other integrated circu...

Abstract

A measurement is taken of an electrical parameter (Vcc) that is approximately proportional to the power consumed by at least a portion of a computer system. This measurement is then used to determineif the power consumed by the portion of the computer system reaches a threshold (150).

Description

[0001] The present invention relates to computer systems, and further relates to limiting the power consumed in a computer system by regulating the power consumed by integrated circuits in response to a high power condition. Background technique [0002] Computer systems, from small handheld electronic devices to mid-sized mobile and desktop systems to large servers and workstations, are becoming more and more common in our society. Computer systems typically include one or more processors. A processor manipulates and controls the flow of data in a computer by executing instructions. In order to provide consumers with more powerful computer systems, processor designers strive to continuously increase the operating speed of the processors. Unfortunately, as processor speed increases, the power consumed by the processor also tends to increase. Historically, the power consumed by a processor has been limited by two factors. First, as power consumption increases, processors ten...
