Module 3 - CPS

What defines a real-time system?

• Performs tasks without any time constraint

• Delivers output irrespective of timing

• Completes tasks and services within a set time frame

• Delivers output only when powered off

In a hard real-time system, missing a deadline:

• Has no impact

• Decreases efficiency slightly

• Is catastrophic

• Can be ignored

Which scheduling algorithm is best for jobs with fixed parameters like release time and deadline?

• Weighted Round Robin

• Priority Scheduling

• Event Driven

• Clock Driven

Which type of scheduling is used for high-speed switching networks?

• FIFO

• • Priority Scheduling

• Weighted Round Robin

• Clock Driven

In Priority Scheduling, a process with the ______ priority gets the CPU first.

• Lowest

• Highest

• Random

• Moderate

What is Priority Inversion?

• When lower-priority tasks run indefinitely

• When high-priority tasks block low-priority tasks

• • When low-priority tasks delay high-priority tasks

• None of the above

Which type of interrupt latency is desirable in RTOS?

• Minimal

• Long

• Medium

• Irrelevant

In RTOS, which type of memory is preferred for the kernel?

• RAM

• ROM

• Flash

• Hard Drive

What does ECU stand for in automotive systems?

• Energy Control Unit

• Electronic Control Unit

• Electric Circuit Unit

• Engine Command Unit

An ECU is responsible for controlling which of the following?

• Only engine functions

• Electrical systems in a vehicle

• Only braking systems

• Air conditioning systems
