ABSTRACT
Real-time applications are raising the challenge of unpredictability. This is an extremely difficult problem in the context of modern, dynamic, multiprocessor platforms which, while providing potentially high performance, make the task of timing prediction extremely difficult. In this paper, we present a flexible distributed run-time application mapping framework for both homogeneous and heterogeneous multi-core platforms that adapts to application's needs and application's execution restrictions. The novel idea of this article is the application of autonomic management paradigms in a decentralized manner inspired by Divide-and-Conquer (D&C) method. We have tested our approach in a Leon-based Network-on-Chip platform using both synthetic and real application workload. Experimental results showed that our mapping framework produces on average 21% and 10% better on-chip communication cost for homogeneous and heterogeneous platform respectively.
