Description

The invention relates to automation, in particular to a logic cell for a recognition matrix.

An object of the invention is to expand the functionality of a cell by being configured to perform various image processing operations.

The drawing shows a block diagram of a cell.

The cell contains the first 1 and second 2 inhibit elements, the first 3 and second 4 AND elements, counter 5, trigger 6, decoder 7, a group of 8,9,10,11 information inputs, the first 12 and second 13 control inputs of the cell, information input 14 cells, outputs 15 ... 19 cells, OR elements 20 and delay element 21.

The device operates as follows.

The initial installation.

Signals equal to 0 and 1, respectively, are supplied to inputs 12 and 13. As a result, a signal is generated at the output of element 2

logical 1, setting counter 5 and trigger 6 to zero. The outputs of the decoder 7 and the outputs 15-16 of the cell will eventually generate logical O signals.

Mode I. Cell programming. The task of programming the cell is to enter into the counter 5 the operation code that is required to be performed when converting the image elements. To this end, a series of pulse signals, the number of which depends on the type of programmed operation, are supplied to the input 12 of the cell. Input 13 in this mode sets a signal equal to zero. B. As a result of a series of pulses from input 12, through element 1, it enters the counting input of counter 5, the change in the state of trigger 6 is blocked by elements 2 and 3. As a result, a binary operation code is generated at the outputs of counter 5 and the cell is configured to execute it. The number of pulses in a series is equal to the value of the binary code of the programmed operation.

Mode I. Recording external data.

The problem to be solved is to enter into the trigger 5 the signal value from the information input 14 of the cell. This operation is performed as follows. At the inputs 12 and 13, a pulse signal equal to one with a predetermined duration is simultaneously supplied. Since in this case the elements 1 and 2 form the O signals at the outputs, the element 5 does not change its state. After a specified time, at the output of element 3, a signal 1 is formed, which arrives at the trigger input of trigger 6. At the same time, the signal from input 14 passes through element 20 to the information input of trigger 6. As a result, the value of the signal is entered into trigger 6, which is required to solve the problem in this mode. In this case, the signal is not distorted by the signal from the output of element 7, since during the existence of the recording pulse, element 4 is blocked by a zero signal from the output of delay element 21, the output of which will be generated by signal 1 only at the end of the action of the signal at inputs 12 and 13. The latter provides blocking writing to trigger 6 of a new output state of element 20.

Mode 111. Record internal data.

The problem to be solved is to write to trigger b the value of the signal generated at the output 19 of the cell. This operation is performed by applying to the inputs 12 and 13 simultaneously a pulse unit signal C P 1 of a given duration and setting a signal equal to 0 at input 14. In this case, the signal from input 14 does not distort the value of the signal coming from the output 19 of the cell through elements 4 and 20 to the information input of trigger 6 simultaneously with the write synchronization signal. As a result, the value of the signal from the output 19 of the cell is entered into trigger 6.

Modes of data processing.

In this mode, image element conversion operations are performed depending on the eigenvalue of the element at input 14 and the values of the elements of its immediate environment, which are elements located in adjacent rows and columns of the matrix. The type of conversion operation is determined by the state of counter 5. The processing process is performed as follows. Cell programming is in progress (mode I). As a result, a conversion operation code is generated in c-counter 5. The trigger 6 records the value of the signal from input 14 (in mode II or III). As a result, the values of the outputs of 15-18 cells of the matrix and, accordingly, their inputs 8-11 are determined. Thus, at the end of the processes of generating signals at the inputs 8-11 of the cell, a binary code is formed at the information inputs of the decoder 7, composed of the values of the signals at the inputs 8-11 and the outputs of the counter 5. In element 7, the received code is decrypted, as a result which only on one of

of its outputs, a value of 1 is formed if the corresponding condition is met. The conditions are specified in the table. Otherwise, the value O is formed at the outputs of the decoder. As a result, at the output 19

5 cells, the result of the execution of a given operation is formed.

Online Processing Mode. 1 The solution to the problem is to perform a sequence of operations for transforming an image without changing its initial display. This is achieved by sequentially alternating programming, recording and processing modes. In this case, provided

5, the possibility of introducing into the matrix an initial image, setting a processing operation, performing a data conversion, setting a new processing operation, performing a specified transformation, etc.
