Description

Otoiots invention is in the field of computer technology and can be used in data lending equipment. A control device is known comprising a meter, the installation input of which is connected to the device installation input, a control decoder connected to the device input, an OR circuit, an AND circuit, a feedback coder and a control encoder connected to the output of the device. The disadvantages of the known device are low speed and high cost of equipment. The purpose of the invention is to increase the speed of the device and the reduction of equipment. The goal is achieved by the fact that the device contains a register of commands, decoders of commands and counter states, a trigger whose outputs are connected to the first inputs of the AND circuits, whose outputs through the OR circuit are connected to the first inputs of the counter and command register, the second inputs of which are connected to the counting trigger input and the output of the feedback encoder, the input of which is connected to the input of the control encoder 25 and to the output of the control decoder. I correspond, whose inputs through counter and command commands connectors with counter and command register outputs, the installation inputs of the command register 30 and the trigger are connected to the device installation input, and the second inputs of the AND circuits are connected to the corresponding device inputs. The block diagram of the device shown in the drawing. The device contains a command register 1, a command decoder 2, a counter 3, a decoder for 4 states of the counter, a control decoder 5, a control encoder 6, a feedback coder 7, an OR 8 scheme, an AND 9 and 10 scheme, a trigger II. The number 12 denotes the controlled object. The device works in the following way. The first instruction entered by register on register 1 is decoded by command decoder 2 and includes the corresponding control decoder 5, which decrypts the state of the logical condition that is tested in the implemented command code for a given counter state. Using the 4 states of the counter 3 decoded by the decoder, the command is divided into an integer number of time intervals. When the command is executed, the output signals of the control encoder 6 perform the specified operations on the controlled object 12. The control device monitors the state of the controlled object 12 iH at the end

The commands synchronously with the UN frequency, via the feedback coder 7, transfer control to the next command (replaces 1 old command code with a new one in the command register).

At the same time, “Counter 3 is set to the State from which the new command begins. ,

Depending on the state of the controlled object 12, the device changes the status of the trigger AND by the signal from the output of the feedback coder 7 and simultaneously switches the counter input 3 to either of the two clock frequencies at the input of the device at the same time. The new states of trigger 11, counter 3 and command register 1 are set at the end of the signals from feedback encoder 7.

The principle of switching frequency-device operation is used, for example, in solving the problem of message distribution.

When receiving and decrypting a message header, the device operates at a low frequency, corresponding to the operating speed of the information memories.

When processing the results of the header, the device operates at a higher frequency, which is equal to the greater frequency of operation of the logic elements.

Thus, an increase in the speed of the device is achieved by switching the frequency of its operation at the rate of flow of the controlled process, and a decrease in the amount of equipment is provided by increasing the number of composite instructions that are incompatible in time by the operators in one Code.
