Power consumption management system and method in pattern information processing system

Abstract

A power consumption management system and method for a graphics information processing system, comprising: a graphics controller generating first and second display information signals; a memory device connected to the graphics controller, and supporting the graphics controller with the first power The first clock speed in the consumption level generates the first display information signal, and supports the graphics controller to generate the second display information signal of the second power consumption level when there is no parallel terminal part; the bridge loop controller cycles and the first display information signal The connection between the memory devices of the parallel terminal part of the display information signal is interrupted at the same time, and the connection between the memory devices of the parallel terminal part of the second display information signal is interrupted, and depending on whether it uses an internal or external power supply and the state of the internal power supply when using the internal power supply, The time ratio of connection and disconnection in the parallel terminal section is adjusted under the control of the power consumption controller. The present invention prolongs the use time of internal power sources such as storage batteries while reducing internal power consumption.

Description

technical field [0001] The present invention relates to a graphic information processing system included in an information processing system (Information Handling System), and in particular to a power consumption management system and method for managing power of the graphic information processing system. Background technique [0002] As the value and uses of information continue to increase, individuals and businesses are finding additional ways to store and process information. One method (additional equipment) available to the user is the information handling system. The advantage of an information processing system is that it can process, edit, store and / or transmit information or data for official, private and / or other purposes, enabling users to share valuable information. Because information processing necessities, requirements, and technologies vary widely among different users and fields of application, an information processing system is also defined by what infor...

Problems solved by technology

If the portable computer runs on an internal power supply with a specified time limit, and the DDR memory used on the portable computer uses a parallel transmission method, more battery power will be consumed, resulting in a shortened battery discharge time.

However, if the parallel transmission method is not used, the DDR memory cannot perform data transmission at a very high clock speed, and the cost of additionally installing the DDR memory is actually wasted in vain.

[0005] Also, there are other difficulties with the use of DDR memory when the information handling system is running on external power

In information processing systems, DDR memory is driven at high speed regardless of the amount of load that can only be generated according to the running application, resulting in an increase in power consumption
