    Abstract: Display data of a first type for a first display device is fetched from a first portion of a first buffer memory and display data of a second type is fetched from a first portion of a second buffer memory at a first time according to an arbitration control signal and then combined into display data for the first display device. Display data of the first type for the second display device is fetched from a second portion of the first buffer memory and display data of the second type for the second display device is fetched from a second portion of the second buffer memory at a second time according to the arbitration control signal, and then combined into display data for the second display device, which is multiplexed with the combined display data for the first display device into a single display data stream and output.

    Abstract: Disclosed are various embodiments for performing color blending of document objects using GPU hardware of a computer. A computer obtains a document specifying a first object and a second object presented in the document, where a portion of the second object overlaps the first object. The computer renders, on a display device, a presentation of the document, where the rendered presentation including the first object of the document. In response to determining that the document specifies blending the second object with the first object in the overlapping portion, configuring dual-source color circuitry of a graphics processing unit (GPU) of the computer to compute, via a dual-source color blending operation, a result color for the blended first and second objects. The computer renders, on the display device, the second object of the document using the result color for the overlapping portion.
