Efficient Fault-Recovery Technique for CGRA-based Multi-Core Architecture
Yoonjin Kim, Seungyeon Sohn · JSTS Journal of Semiconductor Technology and Science · 2015
In this paper, we propose an efficient faultrecovery technique for CGRA (Coarse-Grained Reconfigurable Architecture) based multi-core architecture. The proposed technique is intra/inter-CGRA co-reconfiguration technique based on a ringbased sharing fabric (RSF) and it enables exploiting the inherent redundancy and reconfigurability of the multi-CGRA for fault-recovery. Experimental results show that the proposed approaches achieve up to 73% fault recoverability when compared with completely connected fabric (CCF).
