摘要：A method for arbitrating display output on a display device of a computersystem comprises comparing a candidate display area with each rendering display area ina rendering collection and each waiting display area in a waiting collection, and

determining whether at least one dependency exists for the candidate display area basedon the comparing step, wherein the candidate display area is placed in the waiting queuewhen at least one dependency exists. The method further includes placing the candidatedisplay 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. Amethod for scheduling display of data on a computer display device includes subdividingpartitions 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 waitingqueue, and adding the candidate display data appropriately to either the renderingcollection or the waiting queue based on at least one conflict existing.
