Abstract: A method for processing data for display on a screen involves encoding, using a first colour space, a first portion of image data intended to be displayed on a first area of the screen and encoding, using a second colour space, a second portion of image data intended to be displayed on a second area of the screen. The encoded first and second portions of the image data are compressed, and transmitted over a link for display on the screen. By using different colour spaces to encode image data that is displayed in different parts of a screen, differences in a users vision and/or aberrations caused by display equipment may be accounted for and so provide an improved user experience. Using different colour spaces for different screen areas may also reduce the amount of data that needs to be transmitted, for example by encoding image data more effectively and/or allowing more efficient compression of data.

Abstract: A heterogeneous multi-core integrated circuit comprising two or more processors, at least one of the processors being a general purpose CPU and at least one of the processors being a specialized hardware processing engine, the processors being connected by a processor local bus on the integrated circuit, wherein the general purpose CPU is configured to generate a first instruction for an atomic operation to be performed by a second processor, different from the general purpose CPU, the first instruction comprising an address of the second processor and a first command indicating a first action to be executed by the second processor, and transmit the first instruction to the second processor over the processor local bus. The first command may include the first action, or may be a descriptor of the first action or a pointer to where the first action may be found in a memory.

Abstract: A method for compositing display data at a remote device to form an image for display involves the remote device receiving (S62) elements of the image, where the image includes display data forming a background layer, display elements forming a foreground layers and an overlay data layer. The remote device receives (S63) sensor information indicating one or more of a position of an eye of a viewer, a direction of focus of the eye of the viewer, and/or a position of a display. It then determines (S64) movement of a line of sight between the eye of the viewer and the display, determines an estimate of a future position of the line of sight at a future time based on the determined movement of the line of sight, and determines (S65) an adjustment to be made to the image based on the future position of the line of sight.

Abstract: Display data of a first type destined for a first display device (220A) is fetched from a first portion of a first buffer memory (26A) and display data of a second type destined for the first display device is fetched from a first portion of a second buffer memory (28A) at a first time according to an arbitration control signal. The fetched display data of the first and second types destined for the first display device (220A) is combined into combined display data destined for display on the first display device (220A).

Abstract: A method, at a host device (10), of managing memory (28) of a display control device (16), the memory (28) being used for storing display data sent from the host device (10) to the display control device (16) for display. The method involves maintaining a map (18) at the host device (10) corresponding to the memory (28) at the display control device, the map (18) indicating locations corresponding to addresses of the memory (28) at which data is stored or not. The map (18) is used to determine a size of a portion of the display data, and a location on the map (18) where the portion of display data would fit into the memory. An address in the memory (28) corresponding to the determined location on the map (18), together with the portion of display data, is then sent to the display control device (16), and the location on the map (18) corresponding to the address in the memory (28) is updated to indicate that the address has data stored in it.
