	abstract = {This paper reports a case study of Design Space Exploration for supporting Run-time Resource Management (RRM). In particular the management of system resources for an MPSoC dedicated to multiple MPEG4 encoding is addressed in the context of an Automotive Cognitive Safety System (ACSS). The runtime management problem is defined as the minimization of the platform power consumption under resource and Quality of Service (QoS) constraints. The paper provides an insight of both, design-time and run-time aspects of the problem. During the prelimiary design-time Design Space Exploration (DSE) phase, the best configurations of run-time tunable parameters are statically identified for providing the best trade-offs in terms of run-time costs and application QoS. To speed up the optimization process without reducing the quality of final results, a multi-simulator framework is used for modeling platform performance. At run-time, the RRM exploits the design-time DSE results for deciding an operating configuration to be loaded for each MPEG4 encoder. This operation is carried out dynamically, by following the QoS requirements of the specific use-case.},

	abstract = {Running multiple applications optimally in terms of Quality of Service (e.g., performance and power consumption) on embedded multi-core platforms is a huge challenge.Moreover, current applications exhibit unpredictable changes of the environment and workload conditions which makes the task of running them optimally even more difficult. This dynamic trend in application runs will grow even more in future applications. This paper presents an automated tool flow which tackles this challenge by a two-step approach: first at design-time, a Design Space Exploration (DSE) tool is coupled with a platform simulator(s) to get optimum operating points for the set of target applications. Secondly, at run-time, a lightweight Run-time Resource Manager (RRM) leverages the design-time DSE results for deciding an operating configuration to be loaded at run-time for each application. This decision is performed dynamically, by taking into consideration available platform resources and the QoS requirements of the specific use-case. To keep RRM execution and resource overhead at minimum, a very fast optimisation heuristic is integrated. Application of this tool-flow on a real-life multimedia use case (described in Chapter 9 of the book of this paper) will demonstrate a significant speedup in optimisation process while maintaining desired Quality of Service.},
