Abstract: The invention provides a method for adaptively adjusting a framerate of a graphic processing unit (GPU). For example, when the GPU workload is high and the temperature of the GPU is close to high temperature, the framerate can be decreased to reduce the workload; when the GPU workload is low, the framerate can be permitted to increase to raise the workload. By the present invention, the GPU is permitted to operate at maximum temperature. The method comprises the steps of: (a) receiving an execution parameter associated with at least one GPU; (b) comparing if the execution parameter is greater than a first reference value; and (c) in the event the execution parameter is greater than the first reference value, increasing a sleep time and power-gating the at least one GPU based on the sleep time to adjust the framerate.

Abstract translation: 本发明提供一种用于自适应地调整图形处理单元（GPU）的帧率的方法。 例如，当GPU工作负载高并且GPU的温度接近高温时，可以减小帧率以减少工作量; 当GPU工作负载低时，可以允许帧率增加以提高工作负载。 通过本发明，允许GPU在最高温度下工作。 该方法包括以下步骤：（a）接收与至少一个GPU相关联的执行参数; （b）比较执行参数是否大于第一参考值; 以及（c）在所述执行参数大于所述第一参考值的情况下，基于所述睡眠时间增加睡眠时间并对所述至少一个GPU进行选通以调整所述帧率。
