    One of the fundamental problems in designing a real-time system is to determine the storage requirements of the data exchange used to connect the communication network and central processor. The difficult part of the problem is to find the amount of data exchange storage needed for input/output buffer storage. In this paper, an analytical method is developed. View full abstract»

    By system, we have in mind the meaning accorded by Webster, “a set of objects united by some form of regular interaction or interdependence.” Change in a system is regarded as change in the properties of the objects or in the relationships between the objects. That is, when one considers a physical system or conceives of a hypothetical system, one perceives certain distinct objects s... View full abstract»

    Recent years have seen the development of several general purpose digital computer programs aimed at simplifying the task of carrying out simulation studies.1 Among these is a program called the General Purpose Systems Simulator (GPSS).2,3 Substantial experience accumulated in the use of this program has led to a number of suggested improvements and the present article descri...

  • A general purpose digital simulator and examples of its application, Part II: Simulation of a telephone intercept system

    Publication Year: 1964, Page(s):35 - 40
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1124 KB)

    This part illustrates an application of the simulator to the design of a system that automatically intercepts specific telephone calls. The various components of this system interact in such a complex manner that simulation was found to be more expedient than mathematical analysis. View full abstract»

    Digital simulation has already been proven effective for urban traffic studies.1ߝ4 However, considerable effort is required to program the computer for simulations of any complexity. View full abstract»

    As discussed elsewhere,1 simulation is useful in studying the control mechanism of a manufacturing enterprise. The simulation involves a model representing both the information and physical systems and permits examination of alternative decision algorithms. View full abstract»

    The production of a digital simulator program, or of any program for that matter, involves two steps: creating the model, then writing the program. Fundamentally, the writing of the program is a technical detail which must of necessity wait upon the creation of the model. Nevertheless, the nature of the machinery available for producing simulation programs is bound to exercise an influence on the ... View full abstract»

  • A character computer for high-level language interpretation

    Publication Year: 1964, Page(s):68 - 78
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1605 KB)

    It is perhaps worthwhile emphasizing again the two points of view from which the system may be seen. On the one hand, it is a direct implementation of a high-level language machine in which the various logical suboperations are rather formalized. On the other hand, it is a character-handling machine, one of whose jobs is the interpretation of a high-level language. View full abstract»

  • Design of an integrated programming and operating system, Part VI: Implementation on the 7040/44 data processing system

    Publication Year: 1964, Page(s):79 - 94
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1725 KB)

    Following the decision to produce IBSYS/IBJOB for the 7090/94, it was decided to implement a similar system for the 7040/44. The transfer of a system of the size and complexity of IBSYS/IBJOB to another machine required a re-evaluation of all parts of the system and considerable new design work. Although generally the 7040/44 Operating System is externally compatible with the 7090/94 IBSYS/IBJOB s... View full abstract»

  • Algorithm for a gear-train problem

    A lathe manufacturer planned to incorporate a gear change that would produce a range of metric pitches in addition to the normal range of English pitches. The problem had previously been resolved by using a special 127-tooth change gear to compound the drive to the feedbox. However, such a large gear was awkward to accommodate and involved a loss of production time whenever a change had to be made... View full abstract»

  • A concordance generator

    Publication Year: 1964, Page(s):104 - 111
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1453 KB)

    The purpose of a concordance is to show the places in a document or a class of documents where each principal word may be found. Typically, the immediate context of a word is exhibited, as well as its location. How the concordance is to be organized, and for what use, will vary from user to user and from occasion to occasion. Until recently, concordances were manually prepared, perhaps the most fa... View full abstract»
