Abstract

Resource mapping on a heterogeneous multi-processor system-on-chip (MPSoC) imposes enormous challenges such as identifying important design points for appropriate resource mapping for improved efficiency or performance, time consumption of exploring all the important design points for each profiled applications, etc. Moreover, incorporating a profiler into integrated development environments (IDEs) in order to achieve more detailed and accurate profiling information? on the application being targeted during runtime such that improved efficiency or performance while executing the application is achieved, the runtime resource management decision to achieve such improved 'reward' has to be utilized in a certain way. In this paper, we propose a hybrid approach of resource mapping technique on DVFS enabled MPSoC, which is suitable for IDE integration due to the reduced design points in our methodology resulting in significant reduction in profiling time. We coined our approach as 'RewardProfiler' (a Reward based design space Profiler), which is well capable of reducing the design space exploration without losing most of the important design points based on our heuristic approach. In our strategy, an application has to be mapped onto the available resources in such a way so that the 'reward' obtained can be maximized. Our approach can also be utilized to maximize multiple 'rewards' (Multivariate Reward Maximization) while executing an application. Implementation of our RewardProfiler on the Exynos 5422 MPSoC reveals the efficacy of our proposed approach under various experimental test cases and has a potential of saving 170x more time in profiling for our chosen MPSoC compared to the state-of-the-art methodologies.
