Problems solved by technology

However, the TF card is only in the power-on state when it is in use, and it is in the power-off state at other times, and it takes a long time to turn on the TF card each time, which makes the terminal device freeze due to the long time for the real-time operating system to access the TF card. resulting in increased power consumption of terminal equipment

Abstract

The embodiment of the invention provides a TF card management method and device, and the method is applied to terminal equipment, and comprises the steps of updating a first residual power switching-on duration of a TF card into a second residual power switching-on duration through a management thread if the TF card does not receive a first instruction in a first time period; determining that theTF card enters a state of waiting for the first instruction under the condition that the second residual power supply turn-on duration is not the first duration, and determining that the second residual power supply turn-on duration is the first residual power supply turn-on duration; and turning off the TF card power supply through the management thread under the condition that the turning-on duration of the second residual power supply is the first duration. By adopting the embodiment of the invention, the energy consumption of the terminal equipment is reduced.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a TF card management method and device. Background technique [0002] Because the real-time operating system can quickly process events and data from the outside world, and the processing results can control the production process or respond quickly to the processing system within a specified time, schedule all available resources to complete real-time tasks, and control all real-time Tasks run in a coordinated manner, with the characteristics of timely response and high reliability, and voice playback and / or video playback have high response speed and reliability. Therefore, real-time operating systems are widely used in voice playback and / or video playback. in the terminal device. [0003] When performing entertainment items such as voice playback and / or video playback, the terminal device needs to obtain the address resources for storing entertainment items such...
