Abstract: The description is directed to systems and methods for rotating the image displayed on an electronic device. The data associated with the displayed image is stored in memory locations, typically in a matrix of rows and columns of pixel data. A position sensor detects the rotational position of the device, and this position is used to control the manner in which data is read from the image model. Specifically, data is read from the image model using a read sequence that varies with the detected position of the device, thereby eliminating the need for making additional copies of the image data to account for device rotation.

Abstract: A system, method, and computer program product for recovering from a memory underflow condition associated with generating video signals are disclosed. The method includes the steps of determining that a first counter is greater than a second counter, incrementing an address corresponding to a memory fetch request by an offset, and issuing the memory fetch request to a memory. The first counter represents a number of pixels that have been read by a display pipeline for a current frame and the second counter represents a number of pixels requested from a memory for the current frame.

Abstract: A graphics server for remotely rendering a composite image and a method of use thereof. One embodiment of the graphics server includes: (1) a graphics renderer configured to render updates for a plurality of graphics windows within the composite image and (2) a display processing unit (DPU) configured to identify changed portions of the composite image and provide the changed portions to an encoder for encoding and subsequent transmission.
