However, as a long range objective we wanted a system capable of handling the documentation for virtually any digital computing device, and aiding in certain design functions. On the surface this appears to be the very task performed by existing DA systems but as it turns out the construction techniques used on the calculator give rise to problems not normally handled by these systems.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115945622","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}

In order to facilitate the programmed control of this new hardware, the NOMAD and MAYBE programming languages were developed. However, while these languages provided the programmer with an effective means of controlling the new hardware, they offered little assistance in meeting the hardware data format requirements. The programmer still would have had to convert his output information from his own internal format to the output format required by the hardware. Similarly, all input from the hardware would have had to be converted by the programmer back to a form suitable for his own use. Moreover, these conversion processes are typically very involved and complicated. In short, the programmer was still not in a position to make easy, efficient, and flexible use of the I/O capabilities of the new hardware system. Thus, the need to provide a layer of general purpose I/O software between the programmer and the hardware was very apparent.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114816611","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}

None of these efforts, however, has been specifically directed to the analysis of the total errors generated in a hybrid computation loop.

The most effective general purpose tool available for carrying out the analysis is a high-speed digital computer. Thus the problem of converting large quantities of analog data to a digital form suitable for use on the computer arises frequently. A number of high resolution analog-to-digital converters which can handle data in the kilocycle range are commercially available, but the majority of signals to be analyzed are those with frequency components in the range from a few megacycles up to a gigacycle or more. For these, ordinary real time A-to-D conversion cannot presently be used.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132218146","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}

An important element in the design of information-retrieval systems and pattern recognition devices is associative memory 5, 10--13, 15. An associative memory is particularly suitable for search of a record from a large file, the sorting of data into an ordered list 9, 10, 12 and the identification of patterns. Cryotron circuits are important components in the construction of an associative memory system. Despite this importance and though cryotron technology has been actively developed for some years, it is still in its infancy.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116230057","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 class of languages it can handle is not easy to characterize by syntactic form, since the system permits syntax specification to be varied freely from statement to statement in a program being scanned; the permitted class includes the best-known programming languages, as well as something closely approaching natural language. We believe that this distinguishes the XPOP processor from the syntax-directed compilers, although it shares with them the fundamental idea that the process of programming-language translation can be usefully generalized by a compiler to which source-language syntax is specified as a parameter.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115074705","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 solenoid array memory is useful for stored programs and tables in computers, character generation and as a combined input and storage device for special purpose computers. It utilizes an associative technique to allow addressing of any of its 1024 sixteen word datacontaining sheets, which completely avoids any need for electrical connections to the data-containing sheets or for any ordering of the sheets within the memory. Each sheet is a very thin printed circuit onto which data is entered by etching or punch-card controlled cutting. The data is inductively interrogated by means of solenoids which pass loosely through the sheets. The sheets are contained in loose-leaf notebooklike magazines which fit into a file drawer.\u0000 The present memory's access time is 0.7 microsecond and its cycle is below two microseconds.","PeriodicalId":126790,"journal":{"name":"AFIPS '64 (Fall, part I)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1964-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115034820","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}
