Single event effects (SEEs) caused by radiation are a major concern when working with circuits that need to operate in certain environments, like for example in space applications. In this paper, new techniques for the implementation of moving average filters that provide protection against SEEs are presented, which have a lower circuit complexity and cost than traditional techniques like triple modular redundancy (TMR). The effectiveness of these techniques has been evaluated using a software fault injection platform and the circuits have been synthesized for a commercial library in order to assess their complexity. The main idea behind the presented approach is to exploit the structure of moving average filter implementations to deal with SEEs at a higher level of abstraction.
