Description

This invention relates to the field of computing.

Isovesny devices for the associative search and reading of information containing sources of coherent light, multipliers of the light flux, optical maps, helper masks, memory matrices, masks, associative features, search features, optical elements “And, logical equalizer, picture adder.

Low reliability of such devices is associated with the use of a large number of active elements.

The purpose of the invention is the superior reliability of the device.

This is achieved by introducing a racer, the input of which is optically connected to the output of the logical equivalence element, and the output to the input of the picture adder, and successively positioned between the mask pattern and the memory matrix, the multiplier and the constriction element.

The drawing shows the block diagram of the malicious device.

The ode contains a source of 1 coherent light, a multiplier 2 of the luminous flux, optical patterns: a matrix of 3 search signs, a matrix of 4 masks, a matrix of 5 associative features, a matrix of 6 memories, the first pattern mask / for selecting the lower bit of all numbers, the second cargin -mask 8 for the allocation of an extra bit for all Numbers, the first 9 and second 10 optical picture elements And, the optical picture element 11 of logical equivalence, the expander 12 pictures for one additional bit before each number, the optical map. ummator 13, replicator 14 additional discharge kalsdogo number na all bits egogo number, picture element 15 na odnN discharge each chnsla.

Information encoding in optical pictures - binary: transparent element

corresponds to unity, and nonproz | cancer - to zero. The numbers shown in the pictures are recorded in any number system that makes it possible to perform operatives-i on the picture adder.

All optical pictures in the device have the same dimensions of elements, size and arrangement of numbers, as well as dimensions, except for picture masks 7 and 8, which are wider by one bit for each number.

Numbers read from the memory array can be recorded, for example, by a matte of photodetectors or transmitted over optical channels for further processing.

The light flux in the device maintains coherence along the entire path and is always normal to the optical elements. The transmission of the light stream in the device is carried out using either scoped systems or fiber optics.

A multiplier of 14 additional bits of each number for all bits of this number can be realized, for example, using the Voloston pr-ism or optical systems containing mirrors and prisms, the extender 12 and the element 15 of the descent of pictures by one bit of each number — using optical masks to highlight a specific part of the picture and prisms: or mirrors to displace these parts.

The device operates in the following sequence.

The light note from the coherent light source 1 is divided into four. The first of these is modulated by the 3 search chrisyac search matrix, the second by the 4 mask pattern, the third by 5 associative search matrix, the fourth by the card: 7 to create a light picture of the units in the lower half of each number. The optical picture elements “And 9 and 10 conduct a masking of the pictures of search signs and associative signs, respectively, with the pattern of masks, which are then transmitted to the element AND logical equivalence. The logical equivalence picture obtained on the AND element falls on the expander 12, which widens it by introducing the highest additional bit of the zero value into each number and feeds the first input of the optical picture adder 13. The latter adds it to the picture of the units in the younger de, which enters the second input of the adder from a) mask-mask 7. The transfer from the younger time, a row occurs on all bits and forms a unit in the additional bit only in those numbers where there were all units in the picture of a logical ambiguities, i.e., with the complete coincidence of the corresponding numbers in the picture

signs of noisk and the picture of associative signs. The unit of extra bit is then extracted using picture-masks 8 and multiplies by all bits of the numbers; multiplier 14. Element 15 narrows:

from the light beams to the standard size, which then highlight the required numbers from the memory |
