Description

The invention relates to computing technology and can & 1t be used in hardware to terminate a computer. A device for interrupting the interrupt register is known, the register is protected by a review epoch and a decoder ti. which is characterized by a large amount of equipment and low speed at Bbisrojje-1 and the allowed interruption. The interrupter device containing the interrupt register, the protection register, the review unit, the copy unit of the reset decoder, the output of the reset decoder is connected to the auxiliary input of the interrupt register, the main input to the corresponding device ID, and the auxiliary input -J. the output of the device and the output of the cod aeoary block, the inputs of which are connected to the corresponding outputs of the powerful outputs of the review block whose first connectors j are connected to the outputs pe – t. a protection gist whose installation input is connected to a protection mask bus. However, the three processing of interrupt requests does not take into account the possibility of their interconnection, and re-. access to the service request program

It travels along each of the incoming cable wires, which increases service time. The aim of the invention is to increase | 5 Result due to preliminary analysis of the incoming requests. In the described device, this is achieved; heme, that it additionally introduces the interaction of requests and the request flow block, the input of the register of interrogations j 1 of the request interconnection is connected with the input of the device, and the outputs are connected with the corresponding j inputs of the reset decoder and the first Bxo-f of the block of request skipping, the output of which is connected with the second inputs of the ebzor unit, and the second inputs with the outputs of the interrupt register, the installation inputs of which.
