Patent ID: 8878825

Claim:
A method of updating an image displayed on a display device, the method comprising: asynchronously storing image data at a memory; setting an indicator to a first state that indicates that said image data has been received subsequent to a previous update of the display device; periodically polling the indicator according to a predetermined polling frequency to determine whether the indicator is set to the first state; in response to the periodic polling determining that the indicator is set to the first state, providing the received image data from the memory to the display device to update at least a portion of said display device to display the image by writing at least a portion of the image data to the portion of the display device, wherein the image data is not written to the portion of the display device unless the indicator is in the first state; and altering the predetermined polling frequency based, at least in part, on a rate at which the image data is asynchronously stored at the memory.
