Description

one .

The invention relates to the field of computer technology and can be used in the construction of storage devices for cylindrical magnetic domains (CMD).

A known CMD divider containing a layer of a magnetically uniaxial material (MOM) with a CMD, on the surface of which magnetically soft applications are arranged, which form the distribution channels of domains l.

The disadvantage of the CMD divider is a small load capacity equal to two.

 The closest technical solution to the invention is a device for copying a CMD containing a magnetically uniaxial film, on the surface of which the input and output channels of the promotion of the CMD, the generator and the annihilator of the CMD 2j are located. A disadvantage of the known device is the insignificant number of copies of the input domain (one copy and one original), as well as low productivity. If it is necessary to obtain a large number of copies from the CMD-original, it is required to successively include several CMD dividers, which leads to a non-linear increase in time costs and narrows the area of their possible application.

The aim of the invention is to increase the speed and increase the load capacity of the device for copying the CMD.

The goal is achieved by the fact that the device contains

10 CMD compressor from serially connected dynamic CMD traps according to the number of copies needed; the first and second inputs of the CMD compressor are connected respectively to the input channel

15 of the advancement and the CMD generator, the first output - with the CMD annihilator, and the remaining outputs - with the corresponding advancement output channels. The drawing shows a schematic diagram of the proposed device.

The device for copying the CMD contains a magnetically uniaxial film 1, on the surface of which the input And and output III channels are located

25 advancing CMD, compressor IV CMD from successively connected dynamo traps (DL) V CMD, the second input and the first output of which are connected respectively to a generator

30 VI and the annihilator VII CMD.

The letters X and Y -VYp4i are designated respectively as CMD-original and CMD-yopii. 1,2,3 and so on marked positions. occupied by CMD under permgshlebevy applications VI11 during operation of the device. --- The proposed device is HHPyeT as follows.

The CMD-original arriving at position 2, channel 11, causes a parallel CMD DL compressor CMD DL from position 1 to position 2V of output channels 111, which leads to their appearance at the device outputs in positions 4 through 0.75 contacts, passed through XMOI - the arrival of the original CMD in position 1. This completes the copying process.

In order to restore the circuit to its original state, it is necessary to fill in the freezes during the copy process with the Resident domains. For this purpose, the domain VI generator generates a sequence from p DMDs, which after a p clock cycle will set the circuit to its initial state. The process of completion is complete. (P + 1) -th and all subsequent CMD, coming from the domain geyerator to the compressor inlet, are channeled through channel 4, 1 to the annihilator of VII domains. Kj: run the review of the work of the circuit, with the speed of the proposed device is not inferior to the speed of the prototype (1 clock versus 1.5 clock cycles).

It should also be noted that. with an increase in the number of copies required; P time spent on the area of the domain-containing film

grow slower than similar poka3aTWH devices, organized on the basis of the Prototype divider.
