Abstract(in English) | Acceptable soft error rate on a VLSI chip varies depending on applications and operating environment so that recent VLSI designers concern reliability specification. In this paper, we propose a novel coarse-grained dynamically reconfigurable architecture, which offers flexible reliability. Introducing a notion of cluster cell, which comprises four execution modules, as a basic element of the proposed architecture, four operation modes (TMR, DMR, SMS, and SMM) can be realized with different redundancy and reliability levels. In the TMR operation mode, which attains the highest reliability level, outputs of three execution modules are voted inside of a cluster cell, making it possible to perform an error recovery without any rollback operations. Evaluation of soft error rates demonstrates that four different reliability levels can be achieved by the proposed architecture. The area of additional circuits to provide flexible reliability accounts for 30.5% of the proposed coarse-grained reconfigurable device. |
