Abstract

The invention provides a power supply management system, comprising a display device; an image processor; a time sequence controller comprising a video frame buffer; and a monitoring control unit which is used for monitoring multiple bus activities of a bus on which the image processor is located and filtering multiple image processing activities corresponding to the image processor from the bus activities, wherein the monitoring control unit also estimates an idle time period of the image processor according to the image processing activities; the monitoring control unit also controls the image processor to suddenly write multiple images to the video frame buffer so that the time sequence controller can play the images written by the image processor on the display device in the idle time period, thus automatically updating a panel.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 22, 2012, an application number of 201210301890.0, and an invention title of "power management system and power management method". technical field [0002] The present invention relates to power management, in particular to a power management system and method for automatically updating a control panel (Panel selfrefresh). Background technique [0003] In traditional display technology, it often consumes a lot of power to use the processor to support the screen to display the picture, because the traditional display device panel still reads the display picture from the system memory or the graphics processor (such as GPU) when the display picture is not updated , and send an interrupt signal to the graphics processor. However, with the advancement of technology, Intel has developed the Panel Self Refresh (Panel Self Refresh) technology in the embedded Di...
