He must learn how to express his problems in algorithmic form in the language, the constraints and idiosyncrasies of the language, and the mechanics of running a program on his computer. If he wishes his programs to be efficient, he must learn which constructions in the language use the machine effectively and which do not. This is complicated by the unpleasant fact that effectiveness in the language may not correspond to effectiveness in the machine. A concise, well constructed statement may use much more machine time than an ungainly structure that does the same thing.","PeriodicalId":438698,"journal":{"name":"AFIPS '70 (Fall)","volume":"108 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":"131496327","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}

Farmer","doi":"10.1145/1478462.1478533","DOIUrl":"https://doi.org/10.1145/1478462.1478533","url":null,"abstract":"The problem treated here is that of detecting faults in digital equipment by applying input sequences at the input terminals and observing output sequences at the output terminals. The checking of digital equipment by input/output tests applied at the terminals is motivated by current and future usage of large-scale integration techniques which make internal test points generally inaccessible for testing purposes. The modeling of digital equipment by finite-state sequential machines and then designing fault-detection tests based on the state table is a general approach. The difficulty is that it results in very long experiments for large state tables, particularly for the case in which the state table does not possess a distinguishing sequence. that is, an input sequence for which the response uniquely identifies the initial state. This paper presents a strategy for designing more efficient fault-detection tests for machines not possessing distinguishing sequences.","PeriodicalId":438698,"journal":{"name":"AFIPS '70 (Fall)","volume":"5 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":"127977232","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}
