Mobile device chip and mobile device controlling method therefor

Abstract

A mobile device chip is provided. The mobile device chip includes a main processor, a multimedia processor, and a direct memory access (DMA) circuit. The multimedia processor is electrically coupled to the main processor. The DMA circuit accesses storage, and the DMA circuit is electrically coupled to the multimedia processor. When the mobile device chip operates in a normal mode, the main processor provides file accessing information of at least part of an audio file stored in the storage to the multimedia processor. When the mobile device chip operates in a power-saving mode, the multimedia processor obtains the data of the at least part of the audio file stored in the storage through the DMA circuit according to the file accessing information provided by the main processor.
