(54) DEVICE FOR THE CONTROL OF MICROPRS GR AM MANY

AUTOMATIC

prfi whose input is connected to the output of the second element OR, and the output was e1x; device output

The drawing is a functional diagram of the device for controlling the firmware of the machine,

The device contains a multi-input element OR 1, delay element 2, elements OR 3, 4, trigger 5, element AND 6, counter 7 and element OR 8.

Operation of the device Based on the fact that the microprogram automat (MPA) in response to an external influence, after a pre-calculated time, gives a response signal to the source of the action (control automaton). MPA is the next signal (command). Further, the exchange of signals (commands) continues until the arrival of the signal. End of operation. Consequently, by checking the presence of the MPA and UA reaction on certain time-known and previously known tervala, the functioning of the MPA and UA, as well as the algorithm of their interaction, can be carried out.

The device works as follows. When a signal arrives from the UA, the start of work on bus 9 through the element OR 3 triggers trigger 5, and the signal from its output allows the clock pulses through bus 10 to pass through the element 6 to the counting input of counter 7,: Counter 7 starts counting during which the response signal from the MPA should be received, for example, a signal indicating that the MPA is ready for operation. This signal, yosgupayuti; through one of the reaction bus 11, performs through the OR elements 1 and 8 reset the trigger 5, resulting in the clock pulses through the element And 6 does not pass; through the element OR the installation of the counter 7 to its original state} delay element 2 and element OR 3 - restart of the trigger 5. Score 7, the clock begins to re-count the time interval T, During this interval, the time & A VA on one of the input 12 busses should give the following signal,; Which will perform the same operations as the signal sent over Shiye 11. Before finishing the work session, the UA gives the last signal to the MPA. In response to this signal MPA

in the time interval T on the bus 13 generates a signal End of work, meaning that the MPA has performed all the necessary operations. This signal through the element OR 4 resets 7, and through the element OR 8 - the trigger 5, after which the device ends with.

If no response is received during the time interval T at the session of work on a kikiko-signal, then a refusal signal will be issued from the output of the counter 7 via the bus 14.

The proposed device allows you to quickly control the exchange of signals at a given time interval in the system by the source (receiver) of information - a data processing device.
