Description

The invention relates to the field of computing technology. And can be used to coordinate the work of a physical random number generator (RNG) on a digital electronic computer (COMPUTER). Known devices for computer RNS sonar, supporting the RNG ruling device and computer communication unit, allow receiving information from the generator according to a predetermined law to distribute random numbers in the pause mode with automatic transition to the execution of the axis program. The drawbacks of the known devices are: the lack of synchronization of the RNG from the clock generator of the computer, which requires interruptions, and access, to the generator, and also makes it impossible to control the operation of the generator during the reproduction; the absence of the need to set the law for the computation of computable numbers and the use of two special commands for working with the computer of the random number generator. The aim of the invention is the elimination of ERIC 1-disbalance. This goal is achieved due to the fact that the operation synchronization unit, the RNG from the computer clock generator, the random code Chgisel distribution code and the block of the assignment of random numbers and terval numbers of random numbers are entered into the device. In this case, a standard command to remove information from the computer’s remote control set is used to access the RNG, since the functions of this command are similar for all types of computers. Diagram of the device shown in the drawing. The device for conjugate an RGS with a computer contains a synchronization unit /, a state ns trigger 2, elements "And 3 and 4, counter 5 and a delay line 6, a control device 7 consisting of trigger 8, elements" And 9- / 7 and an inverter 12, a block for setting the sign of a random number 13, a block for outputting a random number 14 to a block for issuing the distribution law code 15. The device for interfacing the RNG 16 with the computer 17 operates as follows. In the initial state, the RNG 16 permanently generates the case of the first numbers, which are received by all bits, except the sign one, to the random number 14. The sign bit is sent to the 3iiaKa random number 13 block. in it start-up pulses. Each launch emulation produces one random number. In addition, start-up pulses must be continuously applied at a frequency close to 100 kg for the RGS automatic control. The random number obtained using the previous trigger pulse is output in the computer 17 with the RNG 16 at the time of the postullein of the next trigger pulse, i.e. the moment of reception of the random numbers in the computer must coincide with the trigger pulse. In order to satisfy all these conditions, the VO device is designed for conjugation of an RGS i3 computer — a C11-N / I-RNC 16 block is introduced from a computer clock generator 17.

In the case of the absence of circulation, the synchronization block / makes a constant start of the RNG 16 at a frequency close to the SO kHz. At the same time, at the beginning of the operation of the general reset signals from the computer 17, the trigger 2 is set to the zero state. From the bullet output of trigger 2, the resolving signal goes to the element I 4, to the second input of which pulses come from the clock generator of the computer 17. When they coincide, the signals from the output of the element I 4 go to the input of counter 5, the output of which is RNG launch

16, as well as resetting the counter 5 to zero and confirming the zero state of the flush trigger 2 via the l / inia delay 6.

Since for all modern computing computers the main clock frequency is higher than the required frequency of the RNG 16 Starting Pulses, in order to enable it to start from the computer clock, the clock frequency of the computer must be done

17.This is achieved with the help of a counter. 5. The number of bits of the counter depends on the frequency of the computer 17 and the frequency of the start of the RNG / b.

Reception of information from the RNG 16 occurs in a certain clock. the impulse included in the command to the RNG 16. UCH. ITYva, that for automatic control of the RNG 16 should be pereryviy.m and receiving information from it should be on a strictly defined pulse. in the comaid, it is necessary to synchronize computer work / 7 and RNG 16, which is provided by the synchronization unit /.

The trigger 2 is set to one by the pulse, which belongs to the command of the RNG 16, according to the time preceding the impulse to receive information from the RNG 16.

The clock pulse from the output of the “I 3” element goes to the output of the synchronization unit J as the start pulse of the RNG 16, resets the counter 5 and, delayed by the delay line w 6 pa time, prevents the pulse of the computer pulses from the computer 16, resets the trigger 2 B zero. Further, the device operates in the same way as in the absence of circulation.

The control device 7 operates as follows.

From the computer / 7 pa element “P 10 with an ial.chii command to receive information from the RNG 16 is one thing: the signal is a sign of this command and the command to receive the command code. CGI; 1al from the output of the electric element “And 10 sets trigger 1 into one.

The control sigpal from the output of the element “AND 9 until it enters the block for issuing a random number 14 and allows the passage of one such number in E.VM 17.

In addition, this signal goes to the inverter 12 and its output to the element “And, on. the second input of which is a signal “ode comma si niformatschi.i e key typing. At the output of element 11, a signal arises that prohibits the transmission of information from the keypad to the computer 17 upon dialing, searching for the RNG 16. If there is no circulation to the RNG 16, then the trigger 8 remains zero, "And 9 a sigal is formed that prohibits reception of information from the RNG 16. This same signal, passed through the inverter 12, if there is a clear command from the keyboard dialing, allows the output of the And / And signal to allow the output signal to be received receiving information from the keys of the 10th set of the computer control panel 17.

When using the proposed device, the command to call the RNG 16 contains a command feature that allows you to determine the type of command - access to the RNG 16 or removal of information from the keyboard, the code of the distribution law and the sign code of the random number.
