Abstract
The Sesame modeling and simulation framework aims at early and thus efficient system-level design space exploration of embedded multimedia system architectures. So far, Sesame only supported performance evaluation when mapping a single application onto a (multi-processor) architecture at the time. But since modern multimedia embedded systems are increasingly multi-tasking, we need to address the modeling of effects of executing multiple applications concurrently in our system-level performance models. To this end, this paper conceptually describes two multi-application workload modeling techniques for the Sesame framework. One technique is based on the use of synthetic application workloads while the second technique deploys only real application workloads to model concurrent execution of applications. For illustrative purposes, we also present a preliminary case study in which a Motion-JPEG encoder application is executed concurrently with a small synthetic producer-consumer application.
