Description

one

The invention relates to the field of automation and computing.

There are computational cells., Environments on multifunctional magnetic current switches with variable weighting coefficients of inputs, thresholds and code rearrangement of logic.

The disadvantages of the known cells of the computing environment are their complexity (large number of magnetic cores) and low speed.

In order to create a universal cell of a high-speed computing environment (end-to-end transfer) and a simple circuit, the inputs of the forward and inverse transfer values are connected to the inputs of the corresponding write capacitors O and 1 of the magnetic current switches of the operation result generating unit, and the outputs of these windings are connected to the inputs of the respective distribution windings of the magnetic current switches of a multi-threshold logic element; the outputs of the distribution windings are connected respectively to the outputs of direct and inverse transfer.

The prizipirlnaya circuit of the universal cell of the computing environment with the end-to-end transfer to magnetic current switches is shown in the drawing; the vertical lines denote magnetic cores with a rectangular hysteresis loop, the horizontal lines denote busbars, and the inclined lines are windings.

The input cores 1 of the variables and the weighting factor code of the inputs, the cores 2 of the input interaction nodes, the cores 3 specify thresholds, and the threshold cores 4-9 with distribution windings 10 located on them, the control windings 11 and 12 of the input variables,

windings 13 input operation code, windings 14, 15 variable records and threshold windings 16, 17, 18 form a multithreshold logic element with a code rearrangement of logic. The direct or inverse value of the external variable is inputted to the multithreshold element via buses 19. Input 20 serves to receive a digit of the number shifted to the right (when performing the operation "shift to the right) from the neighboring cell and is connected to the output terminals 21 of the adjacent higher bit.

The cores 22 and 23 with the windings located from them form a knot forming the result of the operation, and on the cores

23, the code of the number output from the cell is switched.

Input 24 reads the result of the operation.

The codes for the weighting coefficients of the inputs and the thresholds required for the implementation of

stump operations in the cell are entered on tires 25-32. By skipping the current pulses in shicke 33, bitwise operations are carried out on the multi-threshold cell element, and on buses 34 and 35 - the initial installation of the multi-threshold element cores.

Inputs 36 and 37, respectively, of the direct and inverse transfer values from the previous lower bit, are connected in series with the windings 38 and 39 of the records, respectively, of zero and single values of the operation result on the cores of the operation result formation unit n with the winding threshold cores of the multi-threshold element. The outputs of these threshold windings of the threshold cores are connected to the outputs 40 and 41, respectively, of the forward and inverse transfer values to the next most significant bit.

The code of the number outputted from the cell (direct or inverse) is determined by the operation code recorded on the cores of the code selector switch on code buses 42. To eliminate the demagnetizing currents, during the recording and reading of information, decoupling diodes 43 are installed in the circuits.

Duty cycle for performing any operation

in the universal. The cell consists of four cycles.

In the first cycle, spiked 19, 20, and 24 input the initial information, and from the output terminals 21 in the forward or reverse code (depending on the code entered on buses 42), the result of the operation performed in the previous cycle is read from the cores 22 of the operation result generating unit work / pcheki.

In the second cycle, by passing pulses of current to the buses 25-32, the weighting codes of the inputs and thresholds are written onto the cores 1, 2 and 3 of the multithreshold

an item. At the same time, the magnetized upward current pulses of the variable (inputted in the first cycle) cores 1 and 2, the information from which is not used when performing this operation, are resetted downward, the input in the third cycle by a current pulse passed through the bus 33 to the threshold cores 4- 9 corresponding variables with zero weights. The values of the weighting coefficients of the inputs and the thresholds of the multithreshold element necessary for the implementation of a particular operation are summarized in Table. 1 and 2.

The table shows the bus numbers 25-32, which are used to enter the code of the operation being performed.

And the numbers of the threshold cores 4-9, from which the results of bitwise operations performed in the multi-threshold element are read in the fourth cycle.

In the second cycle, the initial setting signal is supplied to the terminal 36 by the "up threshold cores 4-9 of the multi-threshold element.

By pulsing the current pulses to shnam 42 and 33 in the third cycle, information is entered on the code (direct or reverse) of the number to be derived from the cell and the operation on the multi-threshold element is performed. Moreover, those threshold cores 4-9, for which
