    摘要: Bus transactions in a memory controller are scheduled by storing a set of configuration parameters that define a bus scheduling policy, generating values of a set of dynamic cost functions for each bus transaction, ordering the bus transactions in accordance with the bus scheduling policy to produce ordered bus transactions and generating a memory transaction that is derived from the ordered bus transactions. The memory controller includes one or more control registers for storing the set of configuration parameters, a bus interface operable to capture bus transactions from applications, a set of buffers operable to store the bus transactions and the set of dynamic cost functions and one or more registers operable to store the statistical data and a cost policy. The memory controller selects the order of the bus transactions based on an arbitration and selection policy and generates memory transactions to an external memory.

    摘要: A user interface controller of a handheld electronic device (100) that has a camera that generates video images presents (1005) information on a display (105) of the handheld electronic device, processes (1010) the video images to track a three dimensional position of a directing object (260) that is within a field of view (225) of the camera, generates (1015) a two dimensional position of the directing object that is used to control a corresponding location in a scene on the display, and controls (1020) a function of the handheld electronic device in response to a comparison of the track of the directing device to a virtual surface (805, 810, 920, 925) that is defined relative to the handheld electronic device.

    摘要: A system and method for reducing distance-based distortion in a camera image of an object, where the distanced-based distortion is due to differences in distance from the camera to different parts of the object. In one approach, the distortion is reduced by estimating distances to different parts of the object and then generating a reprojected image of the object dependent upon the estimated distances and upon a virtual viewpoint that is more distant than the camera from the object. In a further approach, the image is warped such that points in the image match corresponding points in one or more stored templates. In a still further approach, if excessive distortion is present in the image, the camera zoom is increased and a magnified image is displayed, prompting a person to move farther from the camera thereby reducing the distortion.
