  • Method and apparatus for facilitating real-time and asynchronous loading and temporally-overlapping of modular multimedia software tasks in a multimedia data processing system
    Patent number: 5630132
    Abstract: A data processing system for executing multimedia applications which interface with multimedia devices that consume or produce at least one of real-time and asynchronous streamed data includes a CPU for execution of one or more multimedia applications and a DSP for processing data including streamed data. A plurality of modular multimedia software tasks may be called by the multimedia application for execution in the DSP. A plurality of data communication modules are provided for linking selected ones of the software tasks with selected others of the software tasks, and linking selected multimedia devices with selected ones of the software tasks. Each of the communications modules allows continuous, real-time and unidirectional communication of streamed data.

  • System for facilitating continuous, real-time, unidirectional, and asynchronous intertask and end-device communication in a multimedia data processing system using open architecture data communication modules
    Patent number: 5625845
    Abstract: A data processing system is provided for executing multimedia applications which interface with multimedia end devices that consume or produce at least one of (a) real-time and (b) asynchronous streamed data. The data processing system includes a central processing unit for data processing operations including execution of the multimedia application, a digital signal processor for processing data including the streamed data, and a plurality of modular components which cooperate to provide a substantially open architecture.

  • System and method for efficiently loading and removing selected functions on digital signal processors without interrupting execution of other functions on the digital signal processors
    Patent number: 5442789
    Abstract: A DSP manager acquires through software techniques configuration and related data for multimedia hardware devices from BIOS device drivers interposed to functionally insulate the resource manager from hardware device specific information. The DSP manager manages tasks executing on hardware devices in a multiple DSP environment. The DSP manager optimally assigns tasks, loads tasks, and removes tasks for a function without interrupting execution of tasks making up other functions.

  • System and method for managing devices on multiple digital signal processors
    Patent number: 5440740
    Abstract: A centralized digital signal processor resource manager acquires through software techniques, configuration and related data for multimedia hardware devices from BIOS device drivers interposed to functionally insulate the resource manager from hardware device specific information. The resource manager manages hardware devices in a multiple DSP environment using a unique software based hardware device identification scheme to identify and manage the location and availability of each hardware device.
