Multifunction Module Design for Improved Logistics Support. Volume I.
Abstract
The objective of the study was to investigate the practicality of applying multifunction self-repair circuit technology to the design of electronic digital equipment. The multifunction module was required to operate in a number of modes whereupon failures of its primary mode would be capable of switching to a secondary mode, thus achieving self-repair thereby reducing the number and types of spares required and significantly reducing the maintenance down time. A theoretical multifunctional self-repair design of the Tactical Modular Display (USA-26) indicated that with an increase in complexity of 25% to 50%, reliability is increased to the equivalent of from 3 to 5 standby redundant units that require from 200% to 400% increase in complexity. A 4-bit, 2-register arithmetic processor was also developed to demonstrate self-repair. The demonstration module can perform ten functions and contains two built-in spares that can replace any of the 4-bit modules through an electronic adaptation code. Thus, the model can sustain three failures before corrective maintenance is required. (Author)
