Increasing Soft Error Resilience by Software Transformation

Developing software in a slightly different way can have a dramatic impact on soft error resilience. This observation can be transferred in a process of improving existing code by transformations. These transformations are of systematic nature and can be automated. In this paper, we present a framework for low level embedded software generation - commonly referred to as firmware -- and the inclusion of safety measures in the generated code. The generation approach follows a three stage process starting with formalized firmware specification using both platform dependent and independent firmware models. Finally, C-code is generated from the view model in a straight forward way. Safety measures are included either as part of the translation step between the models or as transformations of single models.
