The additional circuitry required for high reliability can significantly increase the size, weight and power consumption of the subsystem. Today's spacecraft are smaller and cannot afford the added power and weight or cost of traditional redundant computer subsystems. The high reliability systems that depend on 38510 grade 1 electrical parts are often too expensive. To keep the computer subsystem power, weight and cost to a minimum, the computer could be based on an application specific integrated circuit (ASIC) intensive architecture. With internally redundant ASICs, the computer subsystem can be kept to a minimum size, weight, power while still achieving low cost. Additional features, such as error detection and correction (EDAC) on both the address and data busses, and triply redundant voted control lines add significantly to the reliability of the computer subsystem. Often the computer can easily meet the mission reliability requirements using either all 38510 grade 2 electrical parts or a mix of grade 1 and 2 parts, which greatly reduces system cost.<<ETX>>","PeriodicalId":183796,"journal":{"name":"Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128674049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This joint effort has been carried out under the VHSIC Avionics Modular Processor (VAMP) program. The goal was the development of three advanced avionic modules for the French DoD's and USAF's programs: PMF, a 32-bit military processor originally developed for different uses (Avionics, Navy, Army); NVM module, non-volatile memory (8 mbytes EEPROM); HSDB module, bus interface unit for the High Speed Data Bus (Referring to the AS 4074 Linear Token Passing Bus (LTPB) standard). This effort aims at establishing a high degree of interoperability for future NATO systems. These modules were designed under an equally balanced program in which studies and development were to be shared. The paper outlines the key technical issues in the development of each of these modules. It shows also how these modules are integrated and used in the Wright Laboratory Integrated Test Bed and what could be an associated future development.<<ETX>>","PeriodicalId":183796,"journal":{"name":"Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116457469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vision of this development is to provide a corporate MIS that is user friendly, and provides decision support to all levels of Laboratory personnel. The development included the following phases: organization needs analysis, requirements definition, prototyping, system design, coding, deployment, and operations. Three aspects of the ASTARS MIS program are described: (1) system description including hardware and software aspects; (2) spiral software development process was followed, including application of the principles of total quality management (TQM), and principles of corporate information management (CIM); (3) system performance metrics are used to track operational suitability; critical success factors metrics are used to track corporate status. The ASTARS Program is currently in the initial operational phase. There are over 200 frequent users (57 are \"power\" users). Even in the initial operational phase, management changes have been implemented and efficiencies realized. The ASTARS Program has provided valuable insights into the operations functioning of the organization, and offers potential for significant improvements in business practices.<<ETX>>","PeriodicalId":183796,"journal":{"name":"Proceedings of the IEEE 1993 National Aerospace and Electronics Conference-NAECON 1993","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125759915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
