(54) DEVICE TO CONTROL START

PROGRAMS

one

The invention relates to computing, in particular, devices for controlling the launch of programs in the order of receipt of requests.

A device is known for controlling the service of requests, in the order of arrival, containing OR circuits, groups of trigger triggers, with each queue being connected to a corresponding record valve and a discharge valve, a pulse distributor, an encoder connected to the outputs with a register connected to the output of the device, and the inputs the OR circuit is connected to the device's request inputs; the first outputs are {1-t; the leu of issuing rpynh trigger triggers are connected via the second OR circuits corresponding to each group of triggers of the queue with the inputs of the cipher.

The known device is characterized by low speed.

The purpose of the invention is to increase the speed of the device.

To do this, in the proposed device (the second output of each output valve is connected to the input 1H, connected to the output valve of the alternate trigger, the information inputs of the recording gates associated with a group of priority triggers are connected to the corresponding inputs; Managed more commonly, the aajuiCH valve inlets connected to the triples of the same name in groups of triggers of ocher / nosity are connected to the corresponding outputs of the first-time races, the input of which is connected to the output of the OR circuit, control inputs The output circuits associated with the triggers of the same name in the priority trigger groups are connected to the corresponding output. {and BTopor (i pulse distributor, all (KOTOpoiX) are connected to the control; wmx1 and ii triggering inputs of the device, and output; connected to prohibit the input of the second distribution of shtels impulses.

The drawing shows a block diagram of the proposed 1X device for controlling the “H11H program launch.

The device contains a block 1 control the start of the implementation of tasks, pulse distributors 2 and 3, the trigger 4 controls the cycle of recording requests, block 5 of the installation of the initial state, recording gates 6,

sequence 7d, 1, .... issue valves 8.j, 8, ..., 8.j (P - the number of order thrillers corresponding to the number of positions in the queue), OR 9, 1O and 11 schemes, encoder 12, register 13, to the source of requests 14, tires 15 and 16, counter 17, decoder 18, shift register 19, ven-gal 20, trigger 21.

The subscript in the designation of recording gates, sequence triggers and output gates can vary from 1 to rt, where T1 is the number of types (sources) of requests.

The pulse distributor 2 can be implemented, for example, using the counter 17 and the decoder 18, and the pulse distributor 3rd using the shift register 19, the valve 20 and the trigger 21,

The device works as follows

Requests from the sources of requests 14 are received at the first inputs of the corresponding recording gates 61 and the second,

inputs - through the scheme OR 11 and pulse distributor 2; The request that arrives first is passed by the write valve 6,

1-l

OR 6 and is fixed by trigger 7- or

any of the others (tl-D triggers the order of the column. With the arrival of the second request, the resolving potential appears at the second output of the distributor 2. This opens the gates of the request recording that came second, which is fixed either by a trigger or by some of (tl -1) triggers the sequence of this column,

As a result of the tl request record in each order trigger group, only one trigger will be enabled, while the subscript in the number of the trigger corresponds to the type (or source) of the request, and the subscript in the queue for the type of request.

In parallel with the filling of triggers

sequence 7 -7 sampling occurs

requests for service. Pulse distributor 3 produces a consistent

I are in accordance with the order of receipt for j of the questioning of the priority triggering poll. At the same time from the outputs of the discharge valves

5 a signal is removed that resets the sequence trigger connected to: this output valve and goes to the OR 9 circuit, and from the output of the OR 9 circuit to the corresponding input of the encoder 12, 10 Depending on the number of the excited input, the encoder 12 sets to register 13 the number of the initial command prog. Grams caused by a query of this type

.- After the processing of the program, caused by any request, from the computer, the control input 15 of the device receives a signal I ready to service the following sp: millet. The distributor jj of pulses 3 is started, and the queuing of the flip-flop triggers continues.

: with each choice of request for service from the output of the OR 10 circuit, a signal is received at the inhibitory input 16 of the pulse distributor 3, as a result of which the operation of this pulse distributor is blocked.

The trigger 4 for controlling the cycle of recording requests and the unit 5 for setting the initial 30 state ensure that all the device circuits are brought to the required state for receiving the following O requests.
