Description

one

The invention relates to the field of automation and computer technology and can be used in digital information storage devices.

Known coordinate transformers made on toroidal cores.

However, these transformers have low stability when operating in the sampling systems in three or more coordinates. As a result, linear sampling memories (type Z) are, as a rule, two-dimensional and require a large amount of electronic equipment for their construction.

The purpose of the invention is to simplify and increase the reliability of the linear sampling memory. The goal is achieved by using a coordinate transformer made on a multihole core with central and peripheral holes, with the {N-1) windings of the sample currents passing through one of the peripheral holes of the core and the bias current winding located on the outer bridges of the other peripheral holes memory elements, on the internal bridges of these holes are located the windings of the sampling currents along the coordinate, and through the central hole of the core the winding of the installation goes to the outgoing Noe state.

This design of the coordinate transformer allows L / -dimensional sampling. The smallest number of peripheral holes is two. The largest number of peripheral holes is determined by the expression

d / 17 + 1,

where n is the number of peripheral holes, V is the number of words of the memory cube, N is the number of coordinates of the sample.

FIG. 1 shows the proposed multihole core with windings placed on it; in fig. 2 is a timing diagram of control currents; in fig. 3 - switching circuits of the magnetic flux in the core; in fig. 4 - core hysteresis loop.

As an example in FIG. Figure 1 shows the core of a coordinate transformer for performing four-dimensional sampling along XYZQ coordinates for a magnetic by 4096 words (). The external jumpers (p-1) of the peripheral holes are connected to the coils of the communication with (/ g - 1) numerical memory lines.

On each of the internal jumpers of the holes connected to the numerical ruler, there are windings WQ of the current LQ sample PO coordinate Q. On the external jumper of the “th hole, not connected to the numerical ruler, there are windings Wx, Wy, z, respectively, of coordinate currents IK, IY, z sampling, as well as the current W / s bias winding. A recovery winding AB passes through the center hole.

The principle of operation of the proposed coordinate transformer is convenient to consider the timing diagram (Fig. 2).

Let the reading occur from the third numeric ruler (Fig. 1). In the initial state, all core jumpers are remagnetized in the clockwise direction (Fig. 3, a). When reading, current pulses are simultaneously passed through five windings: Wx, Wy, Wz, WQ, We. Ampervity windings of all coordinate currents are equal to each other:

X

and the amperages of the bias winding are equal to twice the value of the amnergings of the coil of the coordinate current,

  f x The field of the bias winding is opposite in the direction of the field windings of the sample currents.

Under the action of the bias winding field, the operating point on the core hysteresis loop (Fig. 4) is set to position A. The core magnetization occurs only if three coordinate currents x, IY, / z are simultaneously applied. In this case, the outer core jumper is re-magnetized in the counterclockwise direction (Fig. 3, b) and the operating point moves to position B. If at least one of the three coordinate currents is absent, then the external jumper does not peremagnetize, and the operating point moves from A in the position of G.

Winding the sample at the fourth coordinate Q acts as follows. If there is no current / Q, then the magnetic flux, closing along the shortest path, changes along the contour shown in FIG. 3, b. The magnetic fluxes in the outer bridges of all peripheral holes associated with the numerical rulers do not change; consequently, none of the numerical lines undergo any remagnetization.

In the event that simultaneously with the currents

5 X, IY, fz a pulse of current IQ passes through any of the windings, then under the action of this current, which is, as it were, a barring current, the internal jumper / rth of the peripheral hole is held in the initial state of magnetization (Fig. 3, eight). In this case, the external jumper of the ith hole peremagnetizes, and in the winding Wcs, an electromotive force is induced, creating a current / a, reversing the magnetization of the cores of the numerical ruler.

During the write cycle, a current is passed through the recovery winding w of the cores of the coordinate transformers of the cube to the reversal, reversing the entire core of the NICKY in a clockwise direction. Under its influence, the external jumper of the selected A-th hole is reversal in a clockwise direction. A current pulse of opposite polarity passes through the connection winding of a numerical ruler, which is necessary for recording in a numerical ruler.
