Abstract : This DIS program has been successful in demonstrating that a small, potentially low-cost, high order language, airborne computer is possible. Twenty-five of these units have been delivered after extensive testing of both software and hardware compatibility. In addition, DIS Diagnostic Stations, used to host source and object JOVIAL files as well as all necessary programming tools, were also designed, tested, and delivered. The use of a distributed microprocessor system will provide a number of benefits yet to be verified in such programs as Midcourse Guidance Demonstration (MGD), Medium Range Air to Surface Missile (MRASM), and low-cost tactical systems. Integration of various subsystems is facilitated by the use of the DIS distributed, modular architecture. However, even in light of the positive aspects of the DIS systems, a number of concerns have surfaced and must be addressed if such a system is actually projected for use in a full scale engineering development (FSED) weapon system. These concerns either have met with little success (mature hardware and software in a cost-effective production forrm) or no success (establishment of interface standards and specifications).
