Reliable NoC architecture utilizing a robust rerouting algorithm

Abstract

Moving towards reconfigurability is an approach to increase fault tolerance on System-on-Chip design. In this paper, we propose a self-reconfigurable NoC architecture utilizing a robust rerouting method. At first, an offline test strategy for locating system-level faults in NoC switch ports is utilized. Using the information achieved in the test phase, every switch reconfigures itself to avoid routing packets through faulty links by utilizing our local rerouting method. The proposed rerouting method is evaluated using a Transaction-Level platform. Experimental results show that our proposed rerouting method delivers all the packets in a faulty NoC successfully and has a less communication overhead compared to a pure flooding method.
