(54) DEVICE FOR CONNECTING SOURCE AND PROGRAMMING INFORMATION

The invention of computer technology, namely, devices for the acquisition of information sources and receivers, can be used in data exchange systems.

A device for storing a source and a receiver is known, comprising a pulse shaping unit, an encoder, a decoder, registers, AND input and output elements, OR elements, BAN elements, delay elements, recording and reading ring walls, a synchronization unit, and a signal for a service terminator. G.

The drawback of the device lies in the fact that it requires a significant amount of equipment.

It is also known a device for matching the source and receiver of information, containing registers with input to output groups of elements AND, elements OR, AND, a counter and a decoder 12.

The disadvantage of this device is relatively low speed.

The closest to the invention to the technical essence and the achieved result is a device for storing the source and source of information containing a group of registers, groups of elements And, triggers, ring counters for recording and reading Sz.

The disadvantage of the known device is the need for large expenditures of equipment for. its implementation.

The purpose of the invention is to reduce equipment.

This goal is achieved by the fact that in the device for interfacing a source and a source of information containing an array of registers whose outputs are connected to the first inputs of elements AND the corresponding group, an OR element, a ring counter of the records whose outputs are connected to control inputs

20 corresponding registers, a ring read counter, the outputs of which are connected to the second inputs of the AND elements of the corresponding group, trigger ,. 39O), where the information input of the device is connected to the information inputs of the registers, the outputs of the element groups AND the Element OR are connected to the information output of the device, and the first and second control inputs of the device are connected to the push inputs of the ring counters of the write and read, the installation input is connected the installation inputs of the read and write counters and with the damping trigger input, the direct output of which is the output of the device readiness signal for information, the output the second bit of the ring counter of the record is connected to the setup input of the trigger, the inverse output of which is the output of the device readiness signal for information. The drawing shows a block diagram of the device. The device for coupling the source and receiver of information contains the source 1 of information, receiver 2 of information, registers 3-Hz, information input 4 of the device, groups 5 -5g of elements AND, outputs 6 -6 d of registers, element OR 7, outputs -8 d of groups of elements AND , device information output 9, ring counter 10 write ring read counter 11, control inputs 12 and 13 of the device, trigger 14, device setup input 15, device readiness output 16 to receive information, device readiness output 17, information outputs 18 - 18g counting Single 1D, output 19 of counter 11 1%, 2O forward and inverse 21 outputs the trigger 14. The apparatus operates as follows. In the initial state, the signal General reset on input 15 from receiver 2 of information, trigger 14 is set to O, bits 2 ... 8 from getchik 1O and 11 are set to O, inverse output 21 trigger 14, to gf output 2O , at the output 18 of the counter 1O 1 (there is permission to write information to the register 3 / |), at the output 19f of the counter 11 (there is permission to read information from the register through the 5 elements And).
