Top 20 interview questions and answers for Embedded Developer

1. What is an embedded system?

An embedded system is a system that has been specifically designed to perform a specific task or set of tasks. It is typically embedded into a larger system or product and is not intended to be used as a standalone device.

2. What are the main characteristics of an embedded system?

Embedded systems are typically characterized by being:

– Real-time: meaning that they must respond to events within a specific timeframe

– Time-critical: meaning that the correct functioning of the system depends on the timely execution of its tasks

– Resource-constrained: meaning that they have limited memory, processing power, and other resources

3. What are the main types of embedded systems?

The three main types of embedded systems are:

– Microcontrollers: These are systems with a microprocessor and integrated memory and peripherals. They are typically used in applications where cost and space are constrained.

– Digital Signal Processors (DSPs): These are systems that are optimized for processing digital signals. They are typically used in audio and video applications.

– Field-Programmable Gate Arrays (FPGAs): These are reconfigurable systems that can be adapted to different applications. They are typically used in applications where flexibility is required.

4. What are the challenges of embedded system development?

The challenges of embedded system development include:

– Designing for resource constraints

– Meeting real-time deadlines

– Handling interrupts and other asynchronous events

– Managing complexity

5. What is an RTOS?

An RTOS is a real-time operating system, which is a type of operating system that is designed to meet real-time deadlines. RTOSes are typically used in embedded systems.

6. What are the benefits of using an RTOS?

The benefits of using an RTOS include:

– Reduced development time

– Reduced complexity

– Improved real-time performance

7. What are the challenges of using an RTOS?

The challenges of using an RTOS include:

– Increased code size

– Increased development time

– Increased complexity

8. What is an RTOS kernel?

An RTOS kernel is the core of a real-time operating system. It manages the system resources and provides the features and services that applications need to meet their deadlines.

9. What are the features of an RTOS kernel?

The features of an RTOS kernel include:

– Scheduling

– Interrupt handling

– Memory management

– Task communication and synchronization

10. What is an RTOS application?

An RTOS application is a type of application that is designed to run on a real-time operating system. RTOS applications are typically time-critical and resource-constrained.

11. What are the benefits of using an RTOS application?

The benefits of using an RTOS application include:

– Reduced development time

– Reduced complexity

– Improved real-time performance

12. What are the challenges of using an RTOS application?

The challenges of using an RTOS application include:

– Increased code size

– Increased development time

– Increased complexity

13. What is an interrupt?

An interrupt is a type of event that can cause a change in the normal flow of execution of a program. Interrupts can be generated by hardware or software.

14. What are the types of interrupts?

The types of interrupts include:

– Hardware interrupts: these are generated by hardware devices such as timers or I/O devices

– Software interrupts: these are generated by software applications or operating systems

15. What is an interrupt handler?

An interrupt handler is a type of function that is called when an interrupt is generated. The interrupt handler typically performs some action in response to the interrupt.

16. What is an interrupt service routine?

An interrupt service routine (ISR) is a type of function that is called when an interrupt is generated. The ISR typically performs some action in response to the interrupt and then returns to the main program.

17. What is a task?

A task is a type of program that is designed to be executed by a real-time operating system. Tasks are typically time-critical and resource-constrained.

18. What are the types of tasks?

The types of tasks include:

– Periodic tasks: these tasks are executed at regular intervals

– Aperiodic tasks: these tasks are not executed at regular intervals

19. What is a task scheduler?

A task scheduler is a type of program that is responsible for allocating resources to tasks and for deciding when tasks should be executed.

20. What is a real-time system?

A real-time system is a type of system that is designed to meet real-time deadlines. Real-time systems are typically used in embedded systems.
