    The run measure of a switching function has arisen in several contexts as an indication of the complexity, or cost, of a realization of the function. The run measure of a function can be defined in terms of its conventional truth-table representation. The output column of the truth table is an ordered sequence of zeros and ones that are disposed in runs; i.e., groups of like digits, of various len... View full abstract»

    This paper presents methods for realizing simple threshold functions of n arguments by networks of k-input majority gates, where k≪n. An optimal network realization of the 5-argument majority function using 3-input majority gates is given, and it is then generalized by steps with realizations for the (2n-l)-argument majority function (where n = 3, 4, ...) using (2n-3)-input majority gates, ...

    It is suggested that the economics of present large-scale scientific computers could benefit from a greater investment in hardware to mechanize multiplication and division than is now common. As a move in this direction, a design is developed for a multiplier which generates the product of two numbers using purely combinational logic, i.e., in one gating step. Using straightforward diode-transisto... View full abstract»

    A complete set of tunnel-diode logic circuits has been developed. The average delay per logic level is 0.5 nsec (0.5×10¿9 sec). The average dc power dissipation per gate is 100 mw (other gate properties are given in Table I). In order to achieve this Performance, the following new techniques were employed: 1) nonlinear biasing using the tunnel resistor, a new tunneling device; 2) trim... View full abstract»

    A new semipermanent data-storage technique is described which can be used either as a fast multimegabit correlator or as a high-speed digital memory. It consists of an array of long, thin cylindrical solenoids and printed-circuit data planes perpendicular to these solenoids and magnetically coupled to them. Data is stored on the planes in terms of circuit paths which either enclose (1) or bypass (... View full abstract»

    An electron recording system for a high density read-only photographic memory has been developed. The information has been recorded at speeds up to 106 bits/sec with a stotage density of 106 bits/cm2. After processing, the information can be read back optically at 106 bits/sec. The high recording speed given by the electron beam technique makes it possib... View full abstract»

    This paper describes a method for solving, on a standard analog computer, problems with wide dynamic ranges. Specifically treated is the restricted three-body problem, numerous examples of which are presented, as well as comparisons to digital results. Some attendant problems are discussed. Limited dynamic range, capacitor dielectric absorption, and electronic multiplier limitations are described ... View full abstract»

    The complete set of orthogonal functions of binary variables called Walsh functions can be obtained as direct products of the subclass of these functions known as Rademacher functions. The complete set of Walsh functions can be conveniently represented by a square matrix of l's and ¿1's, which, when normalized, is an orthogonal matrix. The correct Rademacher functions to multiply together to obta... View full abstract»

    This report describes a new digital differential analyzer (DDA) technique for computing equations of the form f(x)=c/x (c=constant), which was developed to solve a problem posed by the Systems Laboratory. The major advantages of this new method over conventional DDA methods are: a much smaller truncation error because only one integration is performed, and reduced size of the equipment, since it r...

    Mutual inductance is used to reduce the effect of inductance and thus increase speed. If wires are close together when current is switched from one to another, there is very little change in magnetic field, and consequently, very little energy is necessary to do the switching. Therefore, the effective inductance is small. The required close coupling is obtained by depositing one wire of the pair o... View full abstract»

    This paper describes the application of the solenoid array principle to the problem of word recognition, code recognition, and (in a limited sense), associative memory. The proposed device, based entirely on existing experience with a large character recognition cross correlator, is capable of recognizing one of 24,000 individual English words up to 16 letters long. The simultaneous correlation an... View full abstract»
