Schutzer","doi":"10.1109/MARK.1979.8817291","DOIUrl":"https://doi.org/10.1109/MARK.1979.8817291","url":null,"abstract":"The potential for increased transmission efficiency of military tactical command and control data links through voice/ data integration has increased in importance in recent years. With the introduction of even more sophisticated and automated weapons systems, the requirement for on-line exchange of data among tactically-embedded military computer systems has risen dramatically. Today we are faced with a proliferation of data link requirements for innumerable military systems that span all the services. An already densely populated electromagnetic environment is faced with still greater demands for its scarce bandwidth resources. Adding to this situation is the fact that these very resources that are in such heavy demand are quite fragile in the face of military electronic warfare measures. And, with few exceptions, the means for countering these electronic warfare measures place still greater demands on the already scarce bandwidth resources. All of the above provide the motivation for exploring new avenues and techniques that achieve greater efficiency of transmission resources. Economically, the revolution in digital componentry makes more viable the consideration of a greater degree of voice/ data integration over tactical data links than would have been possible just a few years ago. Namely, competing signal processing techniques—Digital LSI, CCDs and SAWs are pushing the boundaries of technologies and making economically attractive spread spectrum, time division multiple access data link systems and internal multiplexed data distribution techniques which would simplify the integration of voice and data. Finally, with the increased sophistication of military weapon systems, the interrelationships and employment of voice and data in the conduct of war becomes even more intertwined and requires in many cases careful reevaluation and re-enumeration.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122172355","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 network is regular so that each computer is a similar \"building block\" with regard to the number of connecting data buses. The number of buses is small not only because microcomputers are inherently limited in their bus capacity but also because many incident buses lead to switching and \"memory port\" complexity, which is difficult to handle by micro-circuits. Such complexity is one of the reasons why shared memory \"mainframe\" computers are relatively expensive. In essence, the low-degree, regular network approach replaces the hard-wired switching with programmed message-passing. Since the processor node will not be fully utilized by productive computing, some of the capacity can profitably be used for such message-handling.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131000208","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}

These systems are generally called \"multiprocessors\" or \"distributed processors\" and may range in organization from processors sharing a common memory to geographically isolated computer installations connected as a network. The low cost and ease of implementation of LSI microprocessors make them extremely attractive design possibilities for the implementation of general-purpose multiprocessor systems. Furthermore, the MOS technology used to implement the majority of microprocessors limits the instruction execution rates such that many applications are compute bound rather than limited by other system bandwidths. This indicates that a number of microprocessors may be effectively interconnected to increase the general system performance.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116090559","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}
