Claims (2)

This invention relates to a computing technique. A break device is known which contains the interrupt registers igi of protection, a detection unit for enabled interrupts, a block for collecting interrupt signals, including blocks for collecting interrupt signals by the number of groups in a block, and a block for a generalized interrupt signal, a control block, a block for generating a priority group of interrupts, the block of the senior priority of the priority group in the group, the reversible counters and the block for the collection of the counter codes Dl The disadvantage of the device is that it cannot ensure the issuance of priority n interruptions in the operation of a digital system operating in various frequency channels and waiting for a response to requests for information from external subscribers. The closest in technical essence and the achieved effect to the proposed is an interrupt device containing an interrupt register, a protection register, an allowed interrupt detection circuit, an interrupt allowed signal collection circuit, a group collection signal of allowed interferences in a group by the number of groups, signals from groups. containing authorized interrupts, control circuits, code generation scheme for the number of the erasable priority group of enabled interrupts, a counter, a decoder, and a detection circuit for the higher priority interrupt L2J. The known device does not allow to quickly change its modes of operation depending on requests from the general system, which limits its functionality. The purpose of the invention is to expand the functionality of the device by quickly changing the modes of operation. The goal is achieved by the fact that the interrupt device containing the interrupt register, the protection register of the output of which is connected to the first input of the block for detecting allowed interrupts, the block for detecting the higher priority of the interrupt, the request input, the first and second control. the inputs of which are connected respectively with the output of the detected interrupt detection unit, with the first outputs of the decoder and the control unit, the second output of which is connected to the counter input of the counter, the address register, the generalized interrupt register, the input and output switches and the interface block are entered, and output 4 is input the switch is connected to the inputs of the re, interrupts, protection and addresses of the output of the interface block connected to the information input of the input switch and the input of the decoder, the second, third and fourth outputs of which .connected respectively to the control inputs of the input and output switches and with the blocking input of the control unit; the third and fourth outputs of the control unit are connected to the second input of the allowed interrupt register, and the second second information inputs and outputs of which are connected respectively, with the moves of the register of interruptions and the counter and with the third input of the unit for detecting allowed interrupts, the first, second information inputs and the output of the output switch are connected respectively to the outputs of the address register and the detection block of the higher priority interrupt and to the input of the interface block, the input-output of the interface block is the input-output of the device, and the input-output of the control unit is connected to the input-output of the output switch, FIG. 1 shows a block diagram of the device; in fig. 2 shows the control unit circuit; the interrupt device comprises a decoder, an input switch 2, an output switch 3, an address register 4, an overriding priority block 5, a protection register 6, an enabled interrupt detection block 7, an interrupt register 8, a generic register 9 interrupts ,, counter 10, control block 11, interface block 12, device input-output 13, decoder outputs 14-17, trigger 18, differentiation node 19, single pulse generator 20, delay node 21, frequency generator 22, AND element 23. The device, it works conductive manner. Depending on the type of information received from I / O 13 through interface 12, decoder 1 controls the writing of the code either to register 4, to register 6, or to register 8, or to block 5 to signal the end of interrupt processing in the external the system. Regardless of the type of information received, the decoder 1 exits the signal 17, triggering the control unit 1 1. The control unit 11 stops the counter 10, designed to count the real time. Frequency Interrupt Applications The baths with counter 10 arrive at register 9, from where, taking into account interrupt requests from register 8, generalized interrupt requests arrive at the input of block 7 for detecting allowed interrupts. Block 7, depending on the code received from security register 6, blocks the issue of a request for interruptions in block 5 for detecting a priority by priority interrupt. The detection unit 5 of the higher priority interrupt generates an interrupt signal having the highest priority at the moment, and in the case of the presence of a signal that the processing of the previous interruption has finished, sends an interrupt signal through switch 3. In the case of an interrupt signal, switch 3 generates a request to receive information from external system through the input-output 13 and through the block 12. Contraction sends an interrupt signal on which the external system should start the execution of the request for the issuance of information, V Received from the external system we information through the interface unit 12 and the input switch 2 is recorded in the address register 4. At the same time, the decoder 1, with a signal from output 16, triggers switch 3; with this signal, the request for receiving information from the external system is quenched. The switch 3 inputs the next high priority signal to the input-output 13 and the code recorded in the address register 4 at the same time. Simultaneously with the output of the interrupt signal, the switch 3 generates a signal that blocks the operation of the control unit 11. At this, the control unit II starts the counter 10. Thus The introduction of new nodes and links between them and lime nodes allows the functionality of the device to be expanded.
