Description

The invention relates to the field of computer technology and can be used to exchange information between an array of electronic computing machines.

Devices lj for interfacing several computers are known, which contain an information storage unit associated with the main memory, input control input terminals to the performing interworking functions between the computer and input-shvod devices.

The disadvantage of such devices is the design loyalty.

According to the technical solution, the closest to this invention is a device for interfacing a computer with I / O peripheral devices, containing a register block connected by an output to the information input of the input elements block AND, the control inputs of which are connected to the first and second outputs of the control unit connected to the third output

With the first output of the device, and the first and second inputs, respectively, with the control input of the device and the output of the synchronization unit, the first input of which is connected to the first input of the control unit, the first information input of the register unit is the first information input of the device.

The disadvantage of this device is that when arranging the exchange of information between two different-speed specialized machines, a double set of equipment is required. Furthermore, the debugging mode of the work program, requiring the operation of both computers, causes additional equipment to suspend the high-speed 9BN {and enter the corresponding command.

The invention is a simplification of the device.

This is achieved by the fact that the instruction storage unit and the input element block AND are entered into the proposed device, with the first and second outputs 1 of the input of the 6th elements of AND being the first and second information Fibl-Hops of the device, the second information input of which and the output of the command stores are connected to the corresponding information inputs of the block of input elements I, the information output and the uglavlny input of which are connected respectively to the second information input of the block of registers and the fourth output of the block Single control, a fifth output is connected to a control input of the block: faneni commands and is a second output device, a second control input device connected to the second sound control l yuschim input sync block, the command input device connected to yn formational Valid commands the storage block. The drawing shows a block diagram of a device comprising a block 1 of registers, a block 2 of output elements And, a block 3 of input elements And, a block 4 of control block 5 of synchronization, a block 6 of storing commands, a high-speed computer 7, a slow-acting computer 8 and a block 9 of formation teams. The device works as follows. Let, for example, a high-speed M 7 and a slow-acting computer 8 execute one program, and so that the computer 7 is the master and the computer 8 is the slave. In this mode, the computer 7 sends data to the computer 8, the latter processes a certain task from these data and produces the results in: ЖМ 7. If you need to transfer information, M 7 issues a signal on the first control input, start this control unit 4 and the unit 5 sync. Block 4 translates the signal to the control output of the device in EV 8 and allows writing the information word to block 1 of registers, where, if necessary, the format of the computer word 7 is converted into computer word format 8. Upon receiving a signal from the computer 8 via block 5 synchronization unit 4 pack This signal outputs to block 2 and the information word is fed to the second information output of the device in computer 8. Next, control block 4, using synchronization block 5, receives and outputs the corresponding control signals to computer 7 and computer 8, adjusting this way The transfer from the computer 7 to the computer 8. In a similar way, information is transferred from the computer 8 to the computer 7. In this case, the information in block 1 of the register {1 is entered through block 3 of the input elements I from E1LM 8, and then through block 2 is output in computer 7. If one of the computers cannot exchange asynchronously, the device using the command stored in block 6 will interrupt the sending computer at the right time, and this moment is determined a priori, as well as the command in block 6 before starting work. In this case, control block 4, after a specified number of information words transmitted through block 3, rewrites the command to block 1 and then it is entered into the transmitting computer by gating the first or second output of block 2 output valves. Similarly, the exchange of information is carried out in debug mode. In this case, work can be carried out with one of the computers. offline, and the imitation of the signals of the other computer is performed by block b, into which these codes arrive at the command input of the device from the external command generation unit. When operating in the specified mode, in block 6, a set of commands or a separate command can be recorded. The programmer, who controls the work of the program on computer output devices, has the possibility of operative intervention by forming the corresponding commands entered from block 9. Thus, the device provides, with minimal equipment, the exchange of information between two computers that have different speeds and word formats. It should be noted that, if necessary, electrical matching at the inputs of the computer should be installed blocks of pre-transmission amplifiers that ensure the passage of electrical signals.
