Research on the dynamic division and management of resources on multiprocessor system-on-chip

Abstract

To increase the scalability of cores, many methods are used, including Network on Chip(NoC) and cluster-based distributed management scheme. The application-based re-clustering algorithm has been delved deeply, while fixed-sized cluster is less developed, including the core-level fault tolerant scheme under such method. Under such environment, a re-clustering scheme based on fixed-sized cluster was proposed in order to achieve fault tolerance, including dynamic re-clustering algorithm. This modeling of chip was finished on MATLAB, and the proposed dynamic re-clustering algorithm was compared with several other algorithms. Core error injections were did and the Average Manhattan Distance(AMD) of the dynamic re-clustering algorithm was compared with random re-clustering algorithm. The results show that the dynamic re-clustering algorithm is far better than random re-clustering algorithm. Then backup cores to the side of the chip were added, and the dynamic re-clustering algorithm was compared with the same-row-replacing algorithm what was commonly used in industry. The dynamic re-clustering algorithm still shows advantages.
