Response time analysis of parameterized dataflow applications on heterogeneous SW/HW systems

Abstract : In contexts such as embedded and cyber-physical systems, the design of a desired functionality under constraints increasingly requires a parallel execution of different tasks on heterogeneous architectures. The nature of such parallel systems implies a huge complexity in understanding and predicting performance in terms of response time. Indeed, response time depends on many factors associated with the characteristics of both the functionality and the target architecture. State-of-the art strategies derive response time by examining the operations required by each task for both processing and accessing shared resources. This procedure is often followed by the addition or elimination of potential interferences due to task concurrency. However, such approaches require an advanced knowledge of the software and hardware details, rarely available in practice. This thesis provides an alternative "topdown" strategy aimed at extending the cases in which hardware and software response times can be analyzed and predicted. The proposed strategy leverages on dataflow-based application representations and focuses on the response time estimation of reconfigurable applications mapped on both general-purpose and specialized processing elements.
