SU631921A1 - Multichannel arrangement for controlling the sequence of accessing a common user - Google Patents

Description

I

The invention relates to TexmiKo computing, to discrete service systems and can be applied in time division devices for interrogating objects.

Data management devices are known that contain a block of registers, a memory block, a pulse generator, and a counter for switching multi-channel information in certain modes lj.

However, this device is characterized by considerable structural complexity.

Other multichannel devices are known for controlling the sequence of calls to the general consumer, containing and -this register, the first inputs of the cells of which are connected to the corresponding input buses of the device, the outputs of the cells are connected respectively to the first, the inputs of the Nevyody elements of which are connected to the corresponding output tires of the device OR, trigger 2.

The device-EY provides follow-on connection of subscribers to the consumer, however, it also differs in its structural complexity.

The goal of the invention is simple devices. .

The goal is achieved by the fact that in the input device the polling pulse generator, the outputs of which are connected to the second inputs of the elements H, the outputs of the elements AND are connected respectively to the second inputs of the cells of the i-bit register and the inputs of the first element OR, the inputs of the second element OR are connected with the first control inputs of the device, 5 the second control input of which and the outputs of the elements OR are connected to the inputs of the tritp e1ea, the output of which is connected to the third inputs of the elements I.

The drawing depicts the structural scheme 0 of ycTf oficTBa.

output bus trigger 6, elements OR 7.8, the first control inputs of the unit (polling completion terminals) 9-9, the second control input of the device (terminal initial setting) 10, the number 11 polling pulses, the device works in the following way , With the arrival of the application on one of the input buses. The arithmetic of the 1 tf. Its memory on one of the cells 2 | - 2. p-bit register 1, the output of this cell prepares the corresponding element AND (4 4fj) for work, on the other input of which the rasterischyyy loss is received from the zero output of trigger 6 in the case of the end of the user’s work the initial installation, coming from terminal 10 before the device starts working. At the third input of the selected element I 4, the impulse shifted in time from the generator 11 pulses of the survey is received. The output signal from the output of the element And 4 is fed to the input of the device (consumer load), as well as through the element OR 7 to install 1 trigger 6 and reset the corresponding 2 in register 1. cells After the end of work, the consumer, on request, hedgehog issues a signal to terminate the interrogation on the terminals 9j, | which, through element 8, flushes trigger b into O, orthox | x tavlip uel (for processing is followed by vkIf two or more applications arrive at the same time due to interrogation of AND 4 - 4 elements and shifted pulses of the generator 11 interrogation pulses A customer can work without losses in the case of a high-frequency input, f is the number of subscribers, J T is the delay of shifted and pulses from a polling pulse generator 11, Tt is the consumer's busy time for each request. Thus, the proposed multichannel device provides an equal priority discipline of customer service and is much simpler known. Formula of the Invention Multichannel device for controlling the sequence of calls to a general consumer containing K-discharge the register, the first inputs of the cells of which are connected to the corresponding input buses of the device, the outputs of the cells are connected respectively to the first inputs of the elements AND, the output which are connected to the corresponding output device, elements OR, trigger, so as to simplify the device, a polling impulse generator is entered into it, the outputs of which are connected to the second inputs of the elements AND, the outputs of the elements AND are connected to a sort of second input cells L of the bit register and the inputs of the first element I.PI, the inputs of the second element OR are connected to the first control inputs to the device, the second control input of which and the outputs of the elements OR are connected to the trigger input, output which is connected to the third / input elements I.
