Abstract
ion For Multimedia Computing* Kevin Jeffay, David Bennett University of North Carolina at Chapel Hill Department of Computer Science Chapel Hill, NC 27599-3175 USA {jeffay,bennettd}@cs.unc.edu Abstract: Process models for multimedia computing must allow applications to adapt their pattern of execution as resources become scarce or abundant. As processes adapt, it is natural to express their desired performance in terms of a processing rate of application-defined data units or events. We propose a process model wherein processes execute according to a general rate specification of x process executions every y time units. In addition, a separate parameter is used to specify the desired response time for the completion of each execution. In all cases the real-time performance of a rate-based process is predictable. The model is general enough to encompass or extend many of the existing models proposed for multimedia systems. Our model of rate-based execution is described along with a...
