Abstract: This invention is directed to defining quick groups for easily associating keywords with an object (e.g., a media objection) accessible using an electronic device. The user of an electronic device may define several keywords that identify attributes of an object accessible using the electronic device. The user may associate keywords with an object to link the attribute of the keyword with the object (e.g., associate a keyword entitled “vacation” to vacation pictures). The user may assign a shortcut key to each of a subset of the keywords, referred to as quick groups, by which the user may rapidly associate the keyword to an object. In some embodiments, the electronic device may select the shortcut key of a quick group from the letters of the quick group to help the user remember the shortcut key.

Abstract: A method to process digital audio data displays the digital audio data in one or more tracks along a time line in a graphical interface of a computer system and defines arrange regions within the time line of the digital audio data as objects for manipulation. Tracks within a selected arrange region are processed as an entity in accordance with commands received through the graphical user interface.

Abstract: A data processing system comprises one or more processors that each execute one or more operating systems. Each operating system includes one or more applications. The system also comprises an accelerator that provides a shared resource for a plurality of the applications, an input/output module comprising one or more input/output interfaces for the submission of tasks to the accelerator, a hypervisor that manages the allocation of the input/output interfaces to the one or more operating systems and a storage area accessible by the hypervisor and the accelerator. The accelerator is capable of writing one or more selected pieces of information representative of one or more scheduling statistics of the accelerator periodically to the storage area without having received a request for the one or more selected pieces of information from the hypervisor.

Abstract: A data processing system includes one or more processors that each execute one or more operating systems that include one or more applications; an accelerator that provides a shared resource for a plurality of the applications; a storage area accessible by the processors and the accelerator; and one or more input/output interfaces for control of, or the submission of tasks to, the accelerator. To initialise one of the input/output interfaces, one of the one or more processors is capable of sending a first signal to the accelerator; the accelerator is capable of writing one or more selected pieces of information representative of one or more capabilities of the accelerator to the storage area and sending a second signal to the processor; the processor is capable of reading the one or more selected pieces of information from the storage area; and the accelerator is capable of configuring the input/output interface.

Abstract: A data processing system includes one or more processors that each execute one or more operating systems. Each operating system includes one or more applications. An accelerator provides a shared resource for a plurality of the applications and has one or more input/output interfaces for the submission of tasks to the accelerator from an application. A hypervisor manages the allocation of the input/output interfaces to the one or more operating systems and a hypervisor interface enables communication between the hypervisor and the accelerator. The system is capable of being configured such that an operating system that has been allocated an input/output interface is capable of communicating with the accelerator via the input/output interface independently of the hypervisor. A memory management unit is capable of providing an isolated region of a memory for use by the operating system whilst the operating system retains its allocated input/output interface.

Abstract: The invention relates to systems, methods, and apparatus for assessing a musical performance. The musical performance can include a user's performance of a musical instrument. MIDI or audio notes are input and compared to the notes of a music track. An indication is provided to assess the musical performance. The assessment can be on the basis of timing and/or pitch errors.

Abstract: A program product, a graphical user interface, a computer system including such a graphical user interface and method for recording and selecting a region of a media track are described. Such a method comprises storing multiple takes of the same region of a media track and storing a data structure representing a take container to store multiple takes.

Abstract: The antirotational, mechanical lash control mechanism for two reciprocating bodies having opposing cylindrical surfaces uses a radial U-shaped groove in the outer surface of the outer housing; a radial cut in the leg of said U-shaped groove, that extends from the groove into said bore; a U-shaped clip adapted to fit the U-shaped groove, the U-shaped clip having a ledge on a leg of U-shaped clip, where the ledge extends through said cut and into said bore; and a first stop on the outer surface of the inner housing, such that the first stop abuts said ledge to control mechanical lash between the outer housing and the inner housing. To prevent rotation, the ledge has a flat surface that mates to a flat surface on the inner housing.

Abstract: A digital audio processor is described, wherein a graphical user interface is presented on the monitor of the processor to display user actionable control elements in a scene of a real world environment for creating and processing music; the graphical user interface is adapted to activate pre-set functions for generating and processing digital audio data in the digital audio processor for each of the user actionable control elements.
