<p>Provided are a DMA controller, a mobile terminal configured with the DMA controller, and a data transport method based on the DMA controller. The DMA controller comprises: a configuration interface which is connected to an external system bus, and is set to configure an instruction area address and a data area address of the DMA controller, wherein an instruction area is a section of a pre-programmed microprogram stored in a system memory; and a processing engine which is connected to the configuration interface, and is set to interpret the microprogram according to the instruction area address and the data area address. In the present invention, the execution of the DMA controller is configured by a programmable microprogram, thereby being able to realize the transport of complicated data, and reduce the influence of an interruption of the DMA controller on a main processor at the same time, and achieve the effect of improving the system efficiency.</p> |
