摘要： A graphic accelerator including a frame memory and the same interface as a memory of a processor and a graphic accelerating method are provided. The graphic accelerator includes: a frame memory; an accelerator controller having the same interface as a memory of the processor on an input side and recording data, which should be transmitted from the processor to the display device, in the frame memory; and a display DMA (Direct Memory Access) transmitting the data recorded in the frame memory to the display device in a DMA manner. A memory bandwidth of the processor is not reduced even by continuous reading operations based on DMA transmission of the display device, by recording data corresponding to the frame memory in the graphic accelerator disposed outside the processor.
