Problems solved by technology

However, on the other hand, the maximum output current of the battery is also an important parameter that restricts the selection of the battery. If the maximum output current of the battery cannot meet the maximum instantaneous power consumption requirements that may exist in the device, it will lead to power failure and other related problems.
[0003] In fact, the power consumption of the system is much lower than the maximum instantaneous power consumption most of the time. Occasionally, there will be a large current consumption for some time periods. If the required current is greater than the rated output current of the battery, it will cause a failure

Abstract

The invention discloses a control method and device for task running. The method comprises the steps that when a task obtains a CPU use permission, a current current value of a system is acquired; a running current threshold of the task is acquired; the running current threshold is the difference between a maximum instantaneous current value permitted by the system and a power consumption currentvalue of the task; if the current current value is not higher than the running current threshold of the task, the task is run; and if the current current value is higher than the running current threshold of the task, the task is suspended. Through the technical scheme, on the premise of not changing a task scheduling algorithm of the system, task running or suspension can be controlled, the current peak value of the system is reduced, the requirement of equipment on power of a power source is lowered, the model selection range of the power source can be expanded, equipment cost is lowered, and the control method and device are quite suitable for embedded equipment and other products with a strict requirement on power sources. In this way, voltage ripples are reduced, and the stability ofoutput voltage of the power source is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a task operation control method and device. Background technique [0002] With the continuous improvement of people's needs, battery-powered devices, such as mobile phones, tablet computers, wearable devices, etc., pay more attention to battery life in the selection of batteries, and devices with large-capacity batteries also have higher performance in similar products. high competitiveness. However, on the other hand, the maximum output current of the battery is also an important parameter that restricts the selection of the battery. If the maximum output current of the battery cannot meet the maximum instantaneous power consumption requirements of the device, it will lead to related problems such as power failure. [0003] In fact, the power consumption of the system is much lower than the maximum instantaneous power consumption most of the time. Occasionally, there...
