  • 16-bit microprogrammable microcomputer with writable control store

    Publication Year: 1981, Page(s):1 - 6

    The paper describes a simple method for loading the writable control memory of a microprogrammable computer. The user-defined microinstructions are stored in the RAM memory of a support processor and they can be loaded into the control memory of the microprogrammable computer by executing simple commands in the support processor. The 16-bit user-microprogrammable microcomputer, the UMM-16, designe... View full abstract»

  • Fault-tolerant memory with content-recovery capability

    Publication Year: 1981

    We propose a new fault-tolerant memory structure derived from the duplex configuration. In this new structure the memory is split into two elements, and a third element, with the same capacity as each of the others, is added. The third element stores coded information obtained from the information in the other two. Two different implementations, parallel and series, have been developed, and are st... View full abstract»

  • Design of high-speed fully serial tree multiplier

    Publication Year: 1981, Page(s):13 - 20
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (867 KB)

    The paper describes and compares three different designs for a high-speed two's-complement, fullyserial tree multiplier, the first of which uses a correction technique, the second Booth's algorithm, and the third employs sign extension. All three designs, each of which possess advantages for different applications, may be clocked at the ceiling frequency determined by the delay through an adder an... View full abstract»

  • Communication requirements of a distributed computer control system

    Publication Year: 1981, Page(s):21 - 34
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2141 KB)

    The paper gives a tutorial exposition and discussion of the requirements that a distributed computer control system imposes on its internal communication system, and of the various ways in which this requirement can be met. The subject is considered under the following main headings: informationtransfer requirements, performance, reliability, environmental and safety considerations, physical confi...

  • Demand-assigned multiple-access systems using collision-type request channels: stability and delay considerations

    Publication Year: 1981, Page(s):37 - 43
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1041 KB)

    Stability and delay characteristics are developed for a demand-assigned multiple-access (DAMA) scheme which employs multiple message channels and multiple collision-type request channels, and which is capable of high traffic capacity. Trade-offs among delay, stability, and bandwidth utilisation, are investigated using an approximate analysis based on expected value-performance measurements. It is ... View full abstract»

  • Studies on p -t- diagnosable system

    Publication Year: 1981, Page(s):44 - 48
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (602 KB)

    The paper presents an algorithm for testing the probabilistically t-diagnosability of a system represented by a weighted digraph. In the second part of the paper, the design of a probabilistically t-diagnosable system (when the probability of failure of each subsystem is known) is described. View full abstract»
