Abstract: A communication mechanism or facility for enabling interaction with, and control of, a remote presentation engine for presenting a rich media application, such as one written using animated graphics allows the presentation engine to be configured or instructed remotely to perform certain actions, to send requests, and/or to send information, independently of the animated graphics application being executed. The communication facility between a workstation enables a presentation engine to pass a request by the application for resource stored on a workstation—an image file or a data file, for example—thereby creating a virtual file system. Local resource references can thus be maintained in the application during development without having to download all resources to the device in connection with testing.

Abstract: A presentation engine collects information concerning the rendering of the frames of an animated graphics application, such the time taken for rendering the frame and the amount of memory used. This information quantifies the amount of certain computing resources being utilized on a per-frame basis, enabling identification by the authors of the animated graphics application, particularly by the designers of the animated graphics, of frames that are problematic, especially on resource-limited devices. The generation of information does not depend on the animated graphics application being instrumented to generate the metrics. The method is adaptable to any resource-limited device, to which the presentation engine is ported or adapted to run. When executing on a resource-limited device, the information is sent to a workstation for analysis. An analysis tool, which may be a stand-alone program or part of an authoring tool or other program, displays the collected metrics graphically in relation to the frame.

Abstract: A process running on, for example, an embedded device without a floating point unit performs a calculation or series of calculations called for in a program written in an language that specifies floating point representation of all numbers using integer arithmetic, unless or until it must execute the calculation using floating point arithmetic due to presence of a non-integer number. Once this happens, the remaining calculations in the series of calculations are automatically handled using floating point arithmetic. Substantially fewer processor operations are necessary to perform the calculations using integer values than floating point values.
