    A large, extremely fast digital adder with sum selection and multiple-radix carry is described. Boolean expressions for the operation are included. The amount of hardware and the logical delay for a 100-bit ripple-carry adder and a carry-select adder are compared. The adder system described increases the speed of the addition process by reducing the carry-propagation time to the minimum commensura... View full abstract»

    Designs for load-sharing zero-noise core switches have been proposed by Constantine, Marcus, and Chien. Blachman class has proposed a core memory wiring plan which with modification can be converted to a load-sharing zero-noise switch. An examination of these switch plans shows that they have a common relationship to a class of mathematical structures known to mathematicians and statisticians as b... View full abstract»

    A number of the more commonly known magnetic core access switches are combined in a single analytical model. In addition to yielding as special cases the known access switches on which it is based, this model produces many apparently new switches. Relationships among the various parameters in this model are developed in such a way that the designer may choose the number of drivers, the load-sharin... View full abstract»

    A noiseless matrix switch is a selection switch in which, for a given set of inputs, one corresponding output (the selected output) is nonzero while all other outputs are zero; the switch is load-sharing with efficiency one if all nonzero inputs contribute to the selected output with the same sign. This paper develops a general theory of noiseless load-sharing matrix switches, from which many new ... View full abstract»

    The consideration of the transistor as a charge-controlled device as proposed by Beaufoy and Sparkes has proved to be a useful way, both conceptually and analytically, to view the transistor. In this paper the charge-control theory is applied to a number of problems of interest to switching circuit designers. The charge-control theory is briefly reviewed to provide a foundation for the problems co... View full abstract»

    Now that standard Transistor Resistor Logic is well understood and widely used, the possibilities for reducing component count by changing the height of the switching threshold, as measured in units of input, are being explored. This paper presents the worst case design formulation, both steady-state and transient, for such variable-threshold circuitry. In addition there is a brief discussion of t... View full abstract»

    An examination of the properties of a pulse transmission matrix for a storage system is given in detail. An attempt is made to arrive at design criteria for a practical system. It appears that microstrip techniques afford an economic approach to the problem and that technically, impedances of the order of 50 ohms will present optimum over-all performance. Use of conductors of about 1 mm in width a... View full abstract»

    Design factors and operational features of a multiaperture ferrite memory core are discussed showing how a low coercive force, low switching coefficient material may be used for a high-speed coincident current storage device. The formulation, geometry, and important processing variables are given and a method of handling large numbers of asymmetrical cores for electrical test is described. Electro... View full abstract»
