COMMUNICATIONS INTERFACE AND SYSTEM FOR RADIATION RECOVERY OF A MICROPROCESSOR PORTION THEREOF

Abstract

A communications interface and system is configured to allow circumventionrecovery of control after radiation) of a microprocessor portion thereof. The communications interface portion, including a hard memory interface device serves as a communications link to the microprocessor. The system is configured so that a transient upset from prompt gamma radiation is detected and a circuit freeze of the stored information in the system is carried out until the transient subsides. The system then restores the microprocessor to the preirradiation condition and resumes operation. Accordingly, the hard memory interface device of the communications interface, controls a READ operation and CLEAR and WRITE operations in addition to generating signals to control the "handshaking" between the hard memory of the communications interface and the aforementioned microprocessor.
