Known in computing structures and systems are switches that can be used for tunable digital devices with programmed control 1. Typically, in such devices, the setup and adjustment time to solve a particular problem depends on the complexity of the switch and the number of elements in it. It increases dramatically with an increase in the number of configurable switching elements in the system.

The switchboard (Fig. 1) contains a matrix 1 of MN electronic detectors of disconnectors 2, each of which contains k information inputs 3, one information output 4, a bus 5 of the connecting path assembly and a disassembly bus B. The information outputs of 4 electronic search-disconnectors of one row of matrix 1 are connected between each other and connected to the corresponding horizontal output information bus 7 of the commutator. There are MELOID information buses in the switch, each such bus is also connected to the corresponding elements of one of the M elements OR 8 lines. One of the pins of the element OR 8 of the line is connected to one of the corresponding buses 9 of the control and the other) enters 6 to the output of one of the corresponding elements AND 10. The input is red (each of them is connected to the 11th number of the same name and the second the inputs are combined and connected to the output of the common element OR 12 of the switch. The inputs of the common element or 12 are connected to the outputs of the register 13 of the address, The switch also has N elements OR 14 columns, the first input of each of which is connected to the corresponding output of the register 13 The second input is to the information input bus of the switch 15, which has only N information input busses.The output of each of the elements OR 14 columns in each column of matrix 1 is connected to the corresponding information inputs of 3 electronic finder-disconnectors 2, For control, the switch contains N elements 16 delays, N one-shot .17, N first additional elements OR 18 and N second additional elements OR 19. Each of the outputs of the address register 13 is connected to the inputs of the corresponding delay elements 16 and one-time pd 17, whose output is connected to one input of a first additional element, OR 18, the other input of which is connected with the relevant first additional switch control bus 20. However, there are N, the first additional switch control buses 20. The output of each first additional element OR 18 is connected with the corresponding disassembly bus electr-. 2 seekers of 1 matrix of the matrix 1.

Shown in FIG. 2, the electronic searcher-disconnector 2 comprises k switching nodes 22, each of which is a three-input element 23, a trigger 24 and a key 25. Information inputs 3 of the electronic searcher-disconnector 2 are connected simultaneously to the information input of the key 25 and the first input of the element 23 and , the second input of which is connected to the information output 4, and the third bus 5 of the assembly of the connecting path. ; The output of the element 23 is connected to the single input of the trigger 24, the single output of which is connected with the control input .26 of the key 25 of the switching node 22, the electronic finder-disconnector 2 also contains two keys 27, the information inputs of KOTOJXJX are connected to the combined outputs of the key whose 25 switching nodes 22, the control input 26 of the first key 27 through the element NOT 28 is connected to the bus 5 of the connecting path assembly, and the control input 26 of the second key 27 with the bus 6 of the disassembly of the connecting path. The information output of the first key is connected to the output 4, and the output of the second key via the delay element 29 is to the zero inputs of all the flip-flops 24.

The switch works as follows.

Before switching the information, the M-bit binary code is written into the register of number 11, with the help of which AND 10 and OR 8 elements short-term excitation of the corresponding horizontal information lines 7 of the switch is carried out.

At that, elements AND 10 open at the moment when in register 13 of the address the bit corresponding to the number of the adjustable column of matrix 1 is transferred to one state. The signal from this bit through the common element OR 12 goes to the inputs of the AND elements 10, to the inputs corresponding one-shot 17 and item OR 14 column.

The pulse from the output of the one-shot 17 through the first additional element OR 18 will go to the bus 6 disassembly of the connecting path of the electronic seeker-disconnectors 2 of the corresponding column of the matrix 1 (Fig. 1). At the same time, the potential from the output of the corresponding element OR 1 of the column will excite information inputs 3 of these ee of the electronic searcher of disconnectors 2.

As follows from FIG. 2, when these inputs are energized in the selected electronic searchers of the x-disconnectors 2, a second key 27 opens, so the signal from inputs 3 passes through the public keys 25 of the switching nodes 22, as well as the second keys 27 and the delay element 29, throws all triggers 24 to the zero state. Consequently, in the selected column of matrix 1, the previous information will be erased.

Similarly, it is possible to erase information simultaneously in several or at once in all columns of matrix 1. For this purpose, it is necessary to form control signals on the control buses 9 and the first additional control buses 20 of the switch. According to these signals, it is possible to control the process of erasing information simultaneously in different parts of matrix 1. This is especially important when the switch is reorganized into other programs.

After the pulse at the output of the one-shot 17 disappears, the signal at the output of the corresponding

The delay element 16 (FIG. 1) associated with the desired register bit 13 of the address. The signal will pass through the corresponding second additional element OR 19 and excite the tires 5 of the assembly of the connecting path of electronic seekers-disconnectors 2 of the selected column of matrix 1. By this time, horizontal information buses 7 will be excited from the outputs of the elements of the OR lines.

0 and informational inputs 3 of these electronic searcher-disconnectors 2.

In the selected electronic searcher of disconnectors 2, the first collection signal closes the first key 27 through the HE element 28 and prepares the AND 23 elements of the switching nodes 22. At the same time, the second and third signals from the information inputs 3

0 and output 4 are transferred to the unit state through an open element AND 23 triggers 24 switching nodes 22 of the electronic searcher 2, located at the intersection

5 excited horizontal output information bus 7 and the corresponding cflice of matrix 1. A similar process of recording the switching program occurs in the other electronic searchers of x-disconnectors 2

0 of this column matrix 1.

. In the case when it is necessary to adjust several columns of matrix 1 at once, Either in the corresponding bits of the register 13 addresses write 5 logical units, or control signals are formed on the corresponding additional buses 21 of the control.
