Real-time systems often require precise timing for data sampling and control operations.

Real-time systems often require precise timing for data sampling and control operations. Thisis usually achieved through the use of a programmable timer circuit that periodically interruptsthe main processor at precise times.Two seven-segment display digits will be used to display the time in seconds and tenths of asecond (roll over from 9.9 to 0.0 and continue). The stopwatch is to be controlled with twoswitches:Switch 1) start/stop timingSwitch 2) clear the display to 0A loop in the main program is to continuously test these switches to determine when to startthe timer, stop the timer, and reset (clear) the display. Whenever the stopwatch is running, thetimer service routine should update the display every 0.1 second. When the stopwatch isstopped, the display should freeze at the last time value. If the clear switch is activated whilethe stopwatch is stopped, the display should reset to 0.0. The clear switch should have noeffect when the stopwatch is running. When the stopwatch is restarted, the time shouldcontinue from the displayed value. Design the complete system using 8086 and peripherals.
