Top 20 interview questions and answers for Embedded Engineer
1. What is an embedded system?
An embedded system is a computer system with a dedicated purpose within a larger mechanical or electrical system. It is typically programmed to perform a specific task, and is not easily reprogrammed for other purposes.
2. What are the characteristics of an embedded system?
Embedded systems are typically designed to be small and efficient, with a limited number of hardware and software components. They are often designed to operate for long periods of time without human intervention, and may be required to perform their tasks in difficult or dangerous environments.
3. What are the common types of embedded systems?
Common types of embedded systems include control systems, automotive systems, medical devices, industrial machines, and consumer electronics.
4. What are the challenges of embedded system design?
Embedded system design can be challenging due to the need to balance conflicting requirements such as size, power consumption, speed, and reliability. In addition, embedded systems often need to interface with other systems and devices, which can add to the complexity.
5. What are the most common embedded operating systems?
The most common embedded operating systems are Linux and Android. Other popular embedded operating systems include Windows CE, QNX, and VxWorks.
6. What is real-time embedded programming?
Real-time embedded programming is a type of programming that is required to meet strict timing deadlines. This can be a challenge due to the need to account for factors such as interrupts and processor speed variations.
7. What is an RTOS?
An RTOS is an operating system that is designed for real-time applications. RTOSes typically provide features such as preemptive scheduling and deterministic behaviour.
8. What is an interrupt?
An interrupt is an event that causes the processor to stop what it is doing and start executing a special routine known as an interrupt handler. Interrupts can be generated by hardware or software, and can be used to handle events such as button presses or timer expiration.
9. What is a task?
In embedded systems, a task is a unit of work that is typically executed in a periodic or sporadic manner. Tasks can be independent or can be dependent on other tasks.
10. What is a task scheduler?
A task scheduler is a software component that is responsible for deciding which task to execute next. Task schedulers typically use algorithms such as priority-based scheduling or rate-monotonic scheduling.
11. What is a priority inversion?
A priority inversion is a situation where a higher priority task is unable to run because a lower priority task is using a shared resource. Priority inversions can cause problems such as missed deadlines or reduced performance.
12. What is mutual exclusion?
Mutual exclusion is a concept in concurrent programming that is used to ensure that only one process can access a shared resource at a time. This can be achieved by using locks, semaphores, or monitors.
13. What is a semaphore?
A semaphore is a type of synchronization mechanism that is used to control access to a shared resource. Semaphores can be used to implement mutual exclusion or to provide a mechanism for task synchronization.
14. What is a monitor?
A monitor is a type of synchronization mechanism that is used to control access to a shared resource. Monitors provide a more flexible way to synchronize tasks than semaphores, but can be more difficult to implement.
15. What is deadlock?
Deadlock is a situation where two or more processes are unable to continue because each is waiting for a resource that the other process is holding. Deadlock can be prevented by using algorithms such as the Banker’s Algorithm.
16. What is a race condition?
A race condition is a situation where the correct operation of a program depends on the order in which processes execute. Race conditions can be prevented by using synchronization mechanisms such as locks or semaphores.
17. What is a critical section?
A critical section is a section of code that must be executed atomically, without interruption. Critical sections can be protected using locks, semaphores, or monitors.
18. What is an interrupt handler?
An interrupt handler is a routine that is executed when an interrupt occurs. Interrupt handlers typically save the state of the processor and then call the appropriate routine to deal with the interrupt.
19. What is a trap?
A trap is an event that causes the processor to stop what it is doing and start executing a special routine. Traps can be used to handle events such as illegal instruction or memory access errors.
20. What is an exception?
An exception is an event that causes the processor to stop what it is doing and start executing a special routine. Exceptions can be used to handle events such as divide by zero errors or invalid memory accesses.
