Systems with state re-set
J. J. Florentin · The Computer Journal · 1975
Some computer systems, such as operating systems and communications controllers, have to work continuously for long periods. These systems are almost inevitably affected by intermittent errors, and there is a need to develop design methods which minimise the effect of occasional errors. This paper points out that, if some part of a system can be modelled as a finite state machine, then it is sometimes possible to arrange that this part will reset itself to a correct state after an error. The technique has been used in the design of a simple interactive programming system.
