Abstract
A method for dynamically limiting a memory bandwidth of a graphics processing unit (GPU) is applicable to a bandwidth-limited system. The bandwidth-limited system includes an audio/video decoder and a GPU. The method includes detecting a plurality of decoding times of a plurality of frames of an audio/video decoded by an audio/video decoder, and adjusting a max grant amount of a memory bandwidth of a GPU according to the plurality of decoding times of the plurality of frames and a target time. Therefore, in the case where the total memory bandwidth is limited, the memory bandwidth of the GPU is limited by the performance of the corresponding audio/video decoder such that, during audio/video playback, the effect of audio/video playback can be prevented from being affected and at the same time a better graphical user interface can be provided.
