Description

I

This invention relates to the field of computing.

A integro-differentiating device containing reversible adders is known.

The disadvantage of the device is low accuracy.

The proposed device is characterized in that it comprises a series-connected inverter and a delay line through which the device input (output) buses are connected to one of the inputs of each, subsequent to its reversible adder, the other inputs of which are connected respectively to the device input and output buses and the output of the previous reversible adder.

This has improved the accuracy of the device.

The scheme of the proposed device for the case of three reversible adders is shown in the drawing.

The device consists of reversible adders 1-3, inverters 4-6 and delay lines 7-9.

In the general case, the number of reversible adders, inverters, and delay lines corresponds to m, where m is the number of bits of the initially independent variable

The general equation of the proposed device is as follows: L, + A, 1 + DI 0,

where At is the stress vector in the widens of a; at

/ g is the step of changing the function supplied to the a, -, if it is necessary to obtain on tires b, a function equal to the derivative of the input. If you submit the original function to the bi bus, then on the tires a; components of the machine variable vector equal to the integral of the original one will be obtained. It should be noted that the step of changing the function A can also be specified in the general case / n-bit number, the corresponding bits of which are dialed using the basic two-terminal network in a reversible adder according to the multiplication vector of the voltage vector by a constant coefficient.

Voltage vector on tires “С; at the time instant, / - / g is created using delay lines connected by inputs to the buses and ;, delaying per cycle equal to / g. The inverter is a servant for matching the sign in the basic equation of the proposed device.

The tires di are supplied with the components of the transfer vector from the low bit to the high bit, produced from the reset voltage in the reversible low bit accumulators.

In general, the device allows one to perform a reversible operation of the second and hybrid differentiation, taking into account the interdigit connections by the equation, which is used for the integration case:
