(5) DEVICE FOR ENTERING INFORMATION

one

The invention relates to computing and can be used to monitor and diagnose peripheral processors and other devices.

A data transmission multiplexer, P, is known in which fixed-type switches are used to simulate signals external to a device.

The drawback of the device is the reduced speed associated with manual control of diagnostics.

Closest to the proposed device for entering information 2J, containing the encoder, the first register, the first, second, third and fourth elements I.

The drawback of the device is the reduced speed associated with the use of manual input of information.

The aim of the invention is to reduce the speed of the device.

This goal is achieved by the fact that the device for entering information containing the encoder, register, trigger, four AND elements, entered the second and third registers, second and third triggers, one-shot, counter, decoder, fifth element AND, key block and block of elements OR, whose inputs are connected respectively to the first and second inputs of the device, the output is to the input of the encoder, the first output of which is connected to the first inputs of the second and third registers. The second output of the encoder is connected to the input of a one-shot, whose output is connected to the first inputs of the first and second elements And to the input of the first trigger, the output of which is connected to the input of the second trigger and the first input of the third element And, the second input of which is connected to the first inputs of the block keys, the fourth element And, as well as the third input of the device. The third input of the third element I is connected to the second input of the second element I, to the first output of the third trigger and to the first input of the fifth element I, the second input of which is connected to the output of the second trigger and to the input of the third trigger, the second output of which is connected to the second input of the first element And, the output of which is connected to the second input of the second register. The outputs of the second and fifth elements And connected to the second inputs of the third register and the fourth element And, respectively, the outputs of the second and third registers are connected respectively to the second and third inputs of the key block, the output of which is connected to the first input of the first register, the second input of which is connected to the output of the decoder the first and second inputs of which are respectively connected to the outputs of the third element I and the counter, whose input is connected to the output of the fourth element AND the output of the first register is connected to the output of the device oystva On the drawing is a block diagram of the device. The device contains a block of elements OR 1, an encoder 2, a block of keys 3, registers 4-6, input-output channels 7, a one-shot 8, triggers 9–11 elements AND 12–16, a decoder 17, a counter 18. The device works as follows. When monitoring and diagnosing I / O channels, the data in register A is used as information imitating the value of the operational memory. The I / O channel uses the contents of register k when fetching a channel control word (CSC), an address data word (AST) or information. Thus, in this mode, as the operation is performed, the contents of the register must be changed. The register contents can be changed either by using manual control signals sent to the device input 19, or by using automatic control signals received at the input 20. Signals from the output of the block of elements OR 1 are sent to the encoder 2, where they occur It is convenient to encrypt and further write to the registers of the higher 5 or lower 6 bits, depending on the availability of the corresponding permitting potentials from the output of the element 12 and 13. From the encoder 2, moreover, a signal is fed to the input of the one-vibrator 8, Secondly, it generates a pulse with a duration of one clock cycle, which is fed to the input of the trigger9 and to the inputs of the And 12 and 13 elements. 8 Depending on the state of the Trigger P, signals are output from the And 12 or 13 element, allowing the information to be entered into the register 5 or 6. Loslo each record These registers trigger 11 changes its state. Triggers 9 and 10 successively delay the pulse from the output of the one-shot 8. The pulse from the output of trigger 9 enters the input element I 14 and in the presence of permissive potentials at the input 21 of the device and at the output of trigger 11 enters the decoder 17. The presence of the resolving potential from the trigger 11 ensures that the pulse arrives at the enable input of the decoder 17 only at the moment when the byte on registers 5 and 6 is formed. The decoder 17 controls the entry of the generated byte into the register depending on the state of counter 18. Soda The counter of counter 18 is changed by the signal from element I 1b after writing the byte to register 4. The signal from the output of trigger 10 is formed when there is a resolving potential from the output of trigger 11. The information recorded in register k enters the input-output channels 7Using the proposed device allows in addition to manual diagnostics, perform automatic diagnostics under the control of another device (central processor) by automatically entering information into register k, under whose control autonomous work is carried out and I / O channels, which leads to an increase in the speed of the device. The invention The input device containing the encoder, the first register, the first trigger, the first, second, third and fourth elements AND, characterized in that, in order to increase the speed of the device, the second and third registers are entered into it, the second and third triggers , one-shot, counter, decoder, fifth And element, key block and block of OR elements whose inputs are connected to the first and second inputs of the device, respectively, output to the encoder input, the first output of which is connected to the first inputs of the second and third registers, the second output of the encoder is coupled to the input of monostable multivibrator, whose output is connected to first inputs of first and second AND gates and to the input of the first flip-flop, whose output is connected to the input of the second flip-flop and the first input of the third AND gate, the second input of which is under. is connected to the first inputs of the key block, the fourth element I, to the third input device, the third input of the third element I is connected to the second input of the second element I, to the first output of the third trigger and to the first input of the fifth element I, the second input of which is connected to the output of the second trigger and to the input of the third trigger, the second output of which is connected to the second input of the first element And the output of which is connected
