A disadvantage of the Fast Fourier Transform is that all samples of the function must be stored in memory before processing can start. The computation in the Fast Fourier Transform occurs after the receipt of the last sample of the function; there is no processing of the incoming data prior to this point. Thus if there are N samples of each function, and G different functions (in G \"gates\" or \"channels\"), then a total of GN words must be stored in memory.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"8 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":"114957364","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}

Systems must be organized and partitioned to obtain a high gate-to-logic pin ratio in order to maximize the use of wafer components. 2. Efficient use must be made of standard logic cells more complex than current IC chips. 3. Logic cells must be defined to both facilitate automated routing and to allow automated testing with a restricted number of test points. 4. Discretionary interconnect of logic elements must be eliminated or minimized. 5. Sufficient redundancy must be used to insure reliability, facilitate testing, and allow economical interconnect in view of non-100 percent yields.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"1 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":"123138045","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 remote processing system for the APT language APT语言远程处理系统

In general, a majority of the errors which occur in the processing of N/C programs are errors of syntax, and these errors cause nearly as much loss of time in processing as the more complex arithmetic errors. Therefore, any system which could provide a partial or complete interactive APT processing capability would be a valuable aid in reducing processing time. A system has been devised whereby a part programmer can sit at a remote console (teletype, etc.), and directly communicate with the computer. This system can produce output for immediate display or for punching onto a tape. Such a system requires a highly specialized processor which can accept APT language statements, check each statement for detailed errors in syntax, and then perform the necessary computations needed to produce an N/C output tape.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"170 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":"123286274","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}

Time-sharing has been emphasized by those interested in providing interactive (online) access to a computer. On the other hand, there are a number of other kinds of systems that provide interactive service. First, there are systems like SAGE and the airline reservation systems (Ref., for example). These are single-purpose systems providing the capability for users to communicate directly with a computer to accomplish a well-defined task. Then there are the numerous third-generation operating systems, generally considered to be multiprogrammed systems.
