    The digital computer control of physical processes requires parameters that can be altered digitally. A resistor design is described that provides settings in a wide range with fixed precision. For this purpose a binary floating-point format is used both for expressing the resistor values and for the digital setting. A resistor structure is given that yields values expressed by the above format. I... View full abstract»

    This paper explores some new solutions to the problem of high-speed data reconstruction in real time. Two types of nonresetting data reconstructors are developed. Both types are simpler than the classical extrapolative hold circuits and when optimized give better performance. The optimization procedure is given and results of simulation studies are included.

    The research reported in this paper is concerned with the use of functional analysis and operator theory in providing insights into iterative computational methods. The computational methods are discussed in the context of obtaining the closed-loop response of a complex feedback system on a hybrid computer. The need for iterative solution arises in problems in which the feedback cannot be computed... View full abstract»

    This paper deals with a fault detection and diagnosis technique based on Boolean differences. A brief review of the notion of a Boolean difference is presented, and the concept of partial Boolean difference is introduced. An algorithm for obtaining minimal, complete sets of test-input sequences based on the partial Boolean differences of a switching function is formulated, and illustrations demons...

  • A Data-Storage Format for Information System Files

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1248 KB)

    In developing its chemical information system, Chemical Abstracts Service (CAS) has built files which require hundreds of millions of bytes of storage and in which data elements may range in length from zero in one instance to several hundred bytes in another. To cope with this size and variability, CAS has developed an internal standardized storage format and has implemented it on the IBM System/... View full abstract»

  • A Novel Parallel Binary Counter Design with Parity Prediction and Error Detection Scheme

    Publication Year: 1971, Page(s):44 - 48
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1176 KB)

    In binary counters, the parity bit is not preserved when the data undergo the counting operation. It is necessary to predict the parity bit that should be used with the correct result. A special design has been devised to share as much hardware as possible between the counter and the parity prediction circuit. This reduces the number of logic gates and gives a more efficient design. The scheme inv... View full abstract»

  • Synthesis of Networks with a Minimum Number of Negative Gates

    Cited by:  Papers (33)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2136 KB)

    In this paper we develop an algorithm to design a switching network using only gates which represent negative functions. The number of gates in the network is minimized under the conditions that 1) the network consists of two levels, and 2) no fan-in restriction on each gate is imposed. View full abstract»

    A family of graph-theoretical algorithms based on the minimal spanning tree are capable of detecting several kinds of cluster structure in arbitrary point sets; description of the detected clusters is possible in some cases by extensions of the method. Development of these clustering algorithms was based on examples from two-dimensional space because we wanted to copy the human perception of gesta... View full abstract»

    In this paper there are developed simple processes for deriving, for finite synchronous sequential machines, polylinear sequential circuit realizations using trigger, set–reset, or J–K flip-flops as the memory elements. It is shown that each such realization is directly obtainable from a graph analogous to the reverse state diagram of the given machine; the latter graph was shown in a ... View full abstract»

    T. A. J. Nicholson has introduced a restricted class of drawn graphs (N-graphs) into the problem of drawing a graph with a minimum number of crosspoints. This short note shows some defects in representing the capability of N-graphs by presenting a planar graph which cannot be represented by any N-graphs. View full abstract»

    A computer control system simulation method utilizing two computers is presented. One is a control computer operating under almost actual conditions. The other is a multiprogrammed computer that simulates the plant. The time taken by the control computer to compute the control variables can be a function of the plant state. An optimum control example illustrating the application of the method is g... View full abstract»

  • Systems of Asynchronously Operating Modules

    This note considers the operation of systems composed of interconnected asynchronously operating modules and shows that some such systems may enter "blocking conditions" in which no module can change state. The model considered applies specifically to asynchronous systems in which each module is controlled only by its neighbors, but may also be relevant to other systems such as parallel computatio...

  • On the Time Necessary to Compute Switching Functions

    In this note we establish a new upper bound on the time to compute classes of switching functions. As did Shannon and Lupanov in their study of the number of elements necessary to compute switching functions, we base our method on a Shannon expansion about a certain number of variables of the function being computed.

    A TANT network is a three-level network composed solely of AND-NOT gates having only uncomplemented inputs. A method of minimal gate TANT realization of a Boolean function is presented. The procedure permits hand solution of four-and five-variable problems. A computer program will be required to handle more complex cases. View full abstract»

  • Conditional Interpretation of Operation Codes

    A method, called conditional interpretation, is proposed which will allow small computers to have as large a set of instructions as may be desired without using a large number of bits to hold the operation code. The method is based on the redundancy of machine language instruction sequences. Most machine language instructions have a limited number of "reasonable" successors. For example "load accu...
