Abstract

Until the digital computer is built which never malfunctions, programmers will have to worry about what will happen to their programs if a machine error does occur. In the case of computers used as integral parts of real-time control systems "worry" is perhaps too weak a word. For a machine error in a computer in such a system may not just cause trouble; it may cause disaster. Thus, with the increasing use of digital computers as elements of real-time systems it has become increasingly important that techniques be developed to handle the malfunction problem in real-time computers. The purpose of this paper is to present a number of such techniques---programming techniques---some well-known and some new for the detection and correction of performance errors in real-time digital computers.
