On State Assignment of Finite State Machines for Soft Error Resilient Stochastic Computing

Abstract (in Japanese) (See Japanese page) 
(in English) Stochastic computing (SC), which is an approximate computation with probabilities, has attracted at- tention owing to its small area, small power consumption and high soft error resilience. In this paper, we focus on the soft error resilience of SC circuits based on linear finite state machines (linear FSMs). We clarify that the memory element of the SC linear FMS-based circuit is vulnerable to soft errors, so that the calculation error of this circuit becomes large if the memory elements suffer from soft errors. Moreover, we formulate the effect of state assignment of this circuit on the significance of the calculation error, and discuss effective state assignment so as to reduce the error. Experimental analysis shows two important points for such state assignment: the relationship between the topological distance and the Hamming distance of two states, and the role of the output functions.
