ABSTRACT:
A method for arbitrating display output on a display device of a computer system comprises comparing a candidate display area with each rendering display area in a rendering collection and each waiting display area in a waiting collection, and determining whether at least one dependency exists for the candidate display area based on the comparing step, wherein the candidate display area is placed in the waiting queue when at least one dependency exists. The method further includes placing the candidate display area in the rendering collection when the at least one dependency does not exist. The method of arbitration includes releasing the current rendering display area. A method for scheduling display of data on a computer display device includes subdividing partitions of an output screen of the computer display device into display areas, determining whether at least one conflict exists between candidate display data, rendering display data in a rendering collection, and waiting display data in a waiting queue, and adding the candidate display data appropriately to either the rendering collection or the waiting queue based on at least one conflict existing.
