Abstract
Apparatus and methods for fast data transfer from a memory or storage device to a display controller. The apparatus comprise a memory, a direct memory access controller operatively coupled to the memory, and a display controller operatively coupled to the direct memory access controller and configured to transfer a data stream from the memory to the display controller. The apparatus may also comprise stored programming configured to set up the display controller with a display address for the data stream, set up the direct memory access controller with a source address for the data stream, a destination address for the data stream, and a size for the data stream, and initiate transfer of the data stream by the direct memory access controller to the display controller. The methods comprise transferring a data stream from a memory to a display controller using a direct memory access controller. The transferring may comprise setting up the display controller with a display address for the data stream, setting up the direct memory access controller with a source address for the data stream, a destination address for the data stream, and a size for the data stream, and initiating transfer of the data stream by the direct memory access controller to the display controller.
