Data compression can substantially reduce the loading of communication channels and error control using coding methodology, can reduce the amount of errors in the messages being transmitted, or allow the system to operate with less power for a comparable uncoded information rate. This paper demonstrates that both functions can be combined into one operation by applying sequential decoding developed for error control to data compression. Because the same general method can be used to solve both problems, data compression and error control can be united in a single system and held accountable for the required theorems in information theory.","PeriodicalId":438698,"journal":{"name":"AFIPS '70 (Fall)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122248485","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}

Most of today's equipment uses parity bits for detection of data transfer errors between units and within units. Error detection for arithmetic data with product or residue type encoding has been used to a limited extent. However, a particularly difficult area for error detection has been control logic. When an error occurs in the control, the machine is likely to assume a state where data is meaningless and/or recovery is impossible. Some presently known methods of checking control logic are summarized below.","PeriodicalId":438698,"journal":{"name":"AFIPS '70 (Fall)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125793114","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}

A desk drawer is conveniently at hand and readily accessible. It contains documents, reports, adversaria---probably most of which, if the work of others, haven't been thoroughly read, or if one's own work, remain unfinished. This material is organized under whatever whimsical scheme suits one's fancy; and as one's fancy changes, the file contents are variously combined or further segregated. (Or at least one would like to perform that kind of reorganization, at present a formidable undertaking.) Needless to add, the texts are set down in a variety of formats, the only common factor among them all being a close adherence to the grammar rules of natural language. Such an unstructured environment is the bane of digital mechanization, but it is to this problem that we have addressed ourselves.","PeriodicalId":438698,"journal":{"name":"AFIPS '70 (Fall)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122401449","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}
