Recently a number of "event-centric" models have been proposed for analyzing multimedia applications running on multiprocessor System-on-Chip (SoC) platforms. This has given shape to a general framework using which different timing and performance analysis questions can be answered in a single coherent manner. Central to this framework is a model for expressing the timing properties associated with different multimedia streams and a means for computing how these properties change as a stream gets successively processed by the different processors of a platform. In contrast to standard event models like periodic or sporadic, this model can accurately capture the datadependent execution time variabilities associated multimedia tasks and the burstiness of on-chip traffic resulting from multimedia processing. In this paper we give a high-level view of this framework, describe setups which currently can be modelled using it, and identify possible directions in which this framework should be extended to make it more usable.
