    Current problems in logic design, in particular those concerned with the design and implementation of digital systems using complex l.s.i. circuits, are discussed. It is argued that established switching theoretic methods, such as minimization, state-assignment etc., are no longer relevant, and that existing theory is inadequate for design at the subsystem level. The difficulties associated with t... View full abstract»

  • Cellular arrays for multiplication of signed binary numbers

    Publication Year: 1974, Page(s):18 - 20

    Two cellular arrays for the multiplication of signed binary numbers using Robertson's algorithm have been described. It has been shown that this results in a considerable saving in hardware compared to previous schemes. View full abstract»

    The past five years have seen the rapid development of iterative circuits performing many arithmetic functions. With the present state of l.s.i. technology in mind, this paper retraces the basic steps made in iterative circuit design and suggests that pipelined arrays are the most suitable for manufacture. The paper also suggests how general arithmetic arrays can be modified to perform non-arithme... View full abstract»

  • Design of NAND logic switching circuits

    Publication Year: 1974, Page(s):27 - 32
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (508 KB)

    Problems in switching theory can be solved using universal NAND logic elements. The design of these circuits is optimized by using a factor procedure to ensure gate minimality with specified fan-in restrictions. The method suggested provides a means of obtaining hand solutions and can be suitably adapted for computer programming. View full abstract»

  • Programmable shift registers for numerical multiplication

    Publication Year: 1974, Page(s):33 - 38
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (851 KB)

    A programmable shift register using `modulo 2¿ or (non-carrying) binary arithmetic is briefly described. The additional problems of making a programmable shift register for numerical binary arithmetic are examined in some detail. An experimental programmable shift register made from standard integrated circuits is described together with performance tests. Various uses of the device are suggested... View full abstract»

  • Adaptive logic for artificially intelligent systems

    Publication Year: 1974, Page(s):39 - 44
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (726 KB)

    The state-of-art of adaptive logic systems consisting of memory elements is surveyed with particular reference to three recent developments. The first introduces the concept of special-purpose structures of mixtures of memory elements and fixed circuitry for the implementation of several logic functions. The second discusses techniques developed for the automatic classification of patterns by mean... View full abstract»

  • The design of sequential logic circuits

    Publication Year: 1974, Page(s):45 - 49
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (685 KB)

    The inadequacies of Combinational and Sequential Logic as circuit design techniques are pointed out; in particular, the Sequential Logic design technique due to Huffman has the disadvantage of leading to `race¿ problems. The work of Moore on Finite Machine Theory points the way to design based on a state graph and this technique is advocated. An illustrative example of this technique is adduced. ...
