Abstract:

The problem considered is the development of design principles which will permit the design of self-diagnosing computers. A self-diagnosing computer is one for which there exists a self-diagnosis procedure, defined as an experiment having one of two outcomes a All transistordiode logic is entirely failure-free or b Card or module x has a failure of type y. Also, the procedure must be sufficiently fast to permit execution every few hours, using non-technical personnel. So little is known about the problems involved in making a computer self-diagnosing, that it is appropriate to first attack a more restrictive, experimental problem. Consequently, an attempt was made to derive a self-diagnosis procedure for the executionphase hardware main control, arithmetic unit, and decoders of an existing machine the CSX-1. The principal experimental tool was the Sequential Analyzer system which allows digital simulation of the class of sequential machines generated under failure from a given machine. Author
