Abstract

Coarse-Grained Reconfigurable Architectures or CGRAs are drawing significant attention since they promise both performance with parallelism and flexibility with reconfiguration. Soft errors or transient faults are becoming a serious design concern in embedded systems including CGRAs since soft error rate is increasing exponentially as technology scaling. A recently proposed software-based technique with TMR (Triple Modular Redundancy) implemented on CGRAs incurs extreme performance overhead mainly due to expensive voting mechanisms for outputs from triplication of every operation. In this paper, we propose selective validation mechanisms for efficient modular redundancy techniques in the datapaths on CGRAs. Our techniques selectively validate results at synchronous operations rather than every operation in order to reduce the expensive performance overhead from the validation mechanism. Our experimental results demonstrate that our selective validation based TMR technique can improve the performance by 38.3% on average over benchmarks as compared to the recently proposed software-based TMR technique with the full validation.
