Embedded Systems Interview Questions & Answers
Describe the pros and cons of using a generic real-time operating system RTOS on a mid-range microcontroller. RTOSes can significantly ease the development of complex products, which can translate into faster development cycles. Because of all that, they also introduce overhead in code size and CPU usage, which is not acceptable for all projects. Interrupt handlers almost always need to finish their execution quickly—the details depend on the device and application—and this limits the complexity of what can be done in their code. Also, the context in which the interrupt handler code is executed can, for either hardware or software reasons, prevent the usage from within the interrupt handler code of:.
Semaphore is simply a variable that is non-negative and shared between threads. This variable is used to solve the critical section problem and to achieve process synchronization in the multiprocessing environment. A watchdog timer is an electronic part of the hardware that detects the computer malfunction and anomalies in the software. During a check for any activity, the timer starts counting from zero and the software restarts. If the software has not restarted and the timer is at zero then it signifies malfunctioning of the software. When you restart the counter of watchdog timer then this process is known as kicking the dog. The watchdog timer is really effective in preventing your system from several dangerous situations by detecting the activity in advance.
The word embedded merely means that something is attached to another thing or system. An embedded system is just like a computer hardware system, but it has software embedded inside the system. It is mainly a part of a bigger system or an independent system. It is based on microprocessors and microcontrollers in order to perform specific tasks. An example of an embedded system is a fire alarm. All the popular Embedded System interview questions and answers have been put together which will be handy if you want to crack an interview. Here in this article, we will be listing frequently asked Embedded Systems Interview Questions and Answers with the belief that they will be helpful for you to gain higher marks.

Download PDF 1 Explain what is embedded system in a computer system? An embedded system is a computer system that is part of a larger system or machine. It is a system with a dedicated function within a larger electrical or mechanical system. With embedded system, it is possible to replace dozens or even more of hardware logic gates, input buffers, timing circuits, output drivers, etc. Real-time embedded systems are computer systems that monitor, respond or control an external environment. This environment is connected to the computer system through actuators, sensors, and other input-output interfaces. The microcontroller is a self-contained system with peripherals, memory and a processor that can be used as embedded system.
