Abstract: Examples of externally-activated devices and systems are disclosed. One example system includes a first device having an actuation component; and a second device having a haptic output component, wherein: the first device and the second device are configured to be physically separable from each other; the actuation component is configured to transmit an actuation signal to the haptic output component while the first device and the second device are physically separated from each other, and the haptic output component configured to output a haptic effect in response to receiving the actuation signal and while the first device and the second device are physically separated from each other, the haptic effect based on the actuation signal.

Abstract: A data processing system has main memory and one or more caches. Data from main memory is cached while mitigating the effects of address pattern dependency. Main memory physical addresses are translated into main memory virtual address under the control of an operating system. The translation occurs on a page-by-page basis such that some of the virtual address bits are the same as some of the physical address bits. A portion of the address bits that are the same are selected and cache offset values are generated from the selected portion. Data is written to the cache at offset positions derived from the cache offset values.

Abstract: A method of optimizing the scheduling of the drawing of graphical elements of a multi-player display (102) in an image processing environment. Each player (801 to 804) is capable of operating asynchronously and deriving its source from a different video, film or other image format. Draw commands from each player are combined into short sequences known as graphics requests (1002 to 1004). A scheduler (821) selects the next graphics request for rendering by a graphics thread (831) based on the requirement to minimize state changes within the graphics card (208) while meeting the due time requirement of the graphics request, that is dependent upon the frame rate.

Abstract: In a computer system, main memory is accessed via a cache. Locations in a main memory are accessed by a process with reference to addresses. Each address comprises virtual bits and physical address bits. Selected bits of the physical address bits identify areas in the cache. Permutations of the selected bits are used to identify buffer alignments in main memory, in response to an identification of requirements for the process.
