In the future, the authors expect commodity hardware to be used in safety-critical applications. However, in the future commodity hardware is expected to become less reliable and more susceptible to soft errors because of decreasing feature size and reduced power supply. Thus, software-implemented approaches to deal with unreliable hardware will be needed. To simplify the handling of value failures, they provide failure virtualization in the sense that they transform arbitrary value failures caused by erroneous execution into fail-stop failures. The latter ones are easier to handle. Therefore, they use the arithmetic AN-code because it provides very good error detection capabilities.
