ABSTRACT:
A computer system includes a main processor and a supervisory processor. The main processor provides status signals when a fault condition exists and responds to control signals for fault recovery. The supervisory processor instantiates objects from a fault class in response to the status signals. Objects are polymorphic in that each object has substantially the same methods available at its interface though each object corresponds to a different fault. Methods accomplish fault recovery by providing the control signals. System operation exhibits fewer errors by the supervisory processor and system expansion is more easily accommodated with greater reuse of proven program code than possible with prior supervisory processor software.
