Abstract
Although computational systems are looking towards post CMOS devices in the pursuit of lower power, the inherent unreliability of such devices makes it difficult to design robust systems without additional power overheads for guaranteeing robustness. As such, algorithmic structures with inherent ability to tolerate computational errors are of significant interest. We propose to cast applications as stochastic algorithms based on Markov chains as such algorithms are both sufficiently general and tolerant to transition errors. We show with four example applications - boolean satisfiability (SAT), sorting, LDPC decoding and clustering - how applications can be cast as Markov Chain algorithms. Using algorithmic fault injection techniques, we demonstrate the robustness of these implementations to transition errors with high error rates. Based on these results, we make a case for using Markov Chains as an algorithmic template for future robust low power systems.
