Evaluation of Fault-Tolerant Routing Methods for NoC Architectures

摘要

This paper presents performance and reliability evaluation of deterministic and adaptive fault-tolerant routing algorithms used in Network-on-Chip (NoC) designs. The investigated methods have a multi-level fault-tolerance capability and therefore can be separately evaluated. To illustrate the effectiveness of these methods, we conduct appropriate simulations on different applications for performance evaluation. But, for reliability assessment, we propose an analytical approach based on combinatorial reliability models to show the effect of fault-tolerant routing algorithms on overall NoC reliability.
