Publication Year: 1960, Page(s):155 - 160
Cited by:  Papers (3)
| | PDF (1759 KB)

A technique is described for detecting specific sequences of pulses occurring on a net of input lines. This technique lends itself to realization in all-magnetic networks by the use of multi-aperture magnetic devices (MAD's). The resulting circuits are remarkably simple and reliable. Processing rates in excess of 100,000 characters per second may be achieved. Examples are given of systems using ar... View full abstract»

• ### Comparison of Saturated and Nonsaturated Switching Circuit Techniques

Publication Year: 1960, Page(s):161 - 175

| | PDF (2226 KB)

The concept that the junction transistor is a charge-controlled current source is reviewed. Saturated operation and non-saturated operation are defined on the basis of minority and majority carrier distributions in the base region. Several common emitter switching circuits are analyzed. The switching efficiency, a figure of merit based on the charge storage properties of the transistor, is introdu... View full abstract»

• ### A New Core Switch for Magnetic Matrix Stores and Other Purposes

Publication Year: 1960, Page(s):176 - 191
Cited by:  Papers (6)
| | PDF (5492 KB)

This paper analyzes the conventional uses of magnetic switch cores to drive matrix stores in both current-driven and voltage-driven modes. A new method of using switch cores is proposed and analyzed which offers, at the cost of replacing in every selection line the usual switch-core and terminating resistor by two smaller cores, intrinsic pulse shaping and amplitude regulation, and much reduced po...

Publication Year: 1960, Page(s):192 - 198
Cited by:  Papers (3)  |  Patents (46)
| | PDF (3477 KB)

Memories using toroidal ferrite cores with cycle timies less than a microsecond are described; the selection ratio is increased by the use of biasing and the multiple coincidence principles of Minnick and Ashenhurst.1 It is shown that this mode of operation leads to important changes in the structure of the store; in particular, the classical core switch does not fulfll the new requirements. The ... View full abstract»

| | PDF (1329 KB)

A twistor is an anisotropic ferromagnetic cylindrical wire with nonmagnetic core. The intrinsic magnetization flux curls in helical sense in the wire and has an air return path. Many field problems must be solved for their successful use as information storage elements. For instance, the demagnetizing field in the wire causes instability of storage and therefore must be reduced by suitable geometr... View full abstract»

| | PDF (1185 KB)

This paper presents the design of a parallel digital computer utilizing a 20-μsec core memory and a diode storage microprogram unit. The machine is intended as an on-line controller and is organized for ease of maintenance. A word length of 19 bits provides 31 orders referring to memory locations. Fourteen bits are used for addressing, 12 for base address, one for index control, and one fo... View full abstract»

• ### An Evaluation of Several Two-Summand Binary Adders

Publication Year: 1960, Page(s):213 - 226
Cited by:  Papers (35)  |  Patents (3)
| | PDF (1792 KB)

Five fairly representative members of the class of two-summand binary adders are described and evaluated. Hopefully, this will help the development of more general approaches to computer subsystems evaluation. The adders are evaluated on the basis of three quantities: the number of two-input AND gates and OR gates, G; the gate-normalized addition time, τ; and the number of bits, n, in each...

Conditional-sum addition is a new mechanism for parallel, high-speed addition of digitally-represented numbers. Its design is based on the computation of `conditional'' sums and carries that result from the assumption of all the possible distributions of carries for various groups of columns. A rapid-sequence mode of operation provides an addition rate that is invariant with the lengths of the su... View full abstract»

• ### Constant-Weight Counters and Decoding Trees

| | PDF (2123 KB)

A class of counters is described in which the number of 1's in the flip-flops or register stages composing the counter remains constant as the counter advances from state to state. Simple digital circuit arrangements are described for the design of such counters, which may be used with a particular type of decoding tree as economical ring-type counters, to provide a separate output lead for each s...

• ### Determination of the Irredundant Normal Forms of a Truth Function by Iterated Consensus of the Prime Implicants

Publication Year: 1960, Page(s):245 - 252
Cited by:  Papers (29)
| | PDF (1618 KB)

This paper describes a new algebraic way of determining irredundant forms from the prime implicants. The method does not require using the developed normal form, and it makes novel application of Quine's technique of iterative consensus-taking. Thus, by applying repeatedly the rule of consensus to the prime implicants, it is possible to derive alist of implication relations that express the necess... View full abstract»

A new electronic slicer circuit produces output pulses whenever a random input voltage x(t) is between two slicing levels X - Δx/2 and X+Δx/2. The slicer pulses gate a counter to produce a direct digital readout count equal to the estimated first-order probability density of the input signal. The system was designed for random process studies with conventional electronic analog com... View full abstract»

An important field of application for computers is in real-time systems simulation. This requires the generation of non-linear functions, obtaining the sums and products of these functions and solving systems of nonlinear differential equations. A new type of analog computer suitable for systems simulation is described which combines the desirable features of the digital and analog computers in it... View full abstract»
