  • Asynchronous notifications for concurrent graphics operations
    Patent number: 8988442
    Abstract: A method and an apparatus for notifying a display driver to update a display with a graphics frame including multiple graphics data rendered separately by multiple graphics processing units (GPUs) substantially concurrently are described. Graphics commands may be received to dispatch to each GPU for rendering corresponding graphics data. The display driver may be notified when each graphics data has been completely rendered respectively by the corresponding GPU.
    Type: Grant

  • Multi-context graphics processing
    Patent number: 8593467
    Abstract: A method of managing multiple contexts for a single mode display includes receiving a plurality of tasks from one or more applications and determining respective contexts for each task, each context having a range of memory addresses. The method also includes selecting one context for output to the single mode display and loading the selected context into a graphics processor for the display.
