The C's volatile keyword is a qualifier that tells the compiler not to optimize when applied to a variable. By declaring a variable volatile, we can tell the compiler that the value of the variable may change any moment from outside of the scope of the program. A variable should be declared volatile whenever its value could change unexpectedly and beyond the comprehension of the compiler.
Embedded Systems based Questions and Answers. What are the characteristics of embedded system? The Characteristics of the embedded systems are as follows- 1. Sophisticated functionality 2.
Real time behavior 3. Low manufacturing cost 4. Low power consumption 5. User friendly 6. Small size. What are the types of embedded system? They are of 4 types 1. General computing 2. Control System 3. Digital Signal Processing 4. Communication and network.
Group discussion topics. What is digital signal controller? DSC is 16 bit RISC machine that combines control advantages of micro-controller and digital signal processing to produce tightly coupled single chip-single instruction stream solution for embedded system design. What are the components of embedded system? Why we use embedded systems? Embedded systems avoid lots of electronic components and they have rich built in functionality.
They reduces the cost and maintenance cost and the probability of failure of embedded system is less so embedded system are in very much use now a days. What are the languages used in embedded system? Java and ADA are also preferred.
How does combination of functions reduce memory requirement in embedded system? By using functions the amount of code that has to be dealt with is reduced thus redundancy is eliminated for everything common in function. What is the significance of watchdog timer in ES? It is a timing device which is set to predefined time interval and some task is to be performed at that time. It is used to reset original state when an inappropriate event take place.
It is usually operated by counter device. What is the difference between mutexes and semaphores? Semaphores are the synchronization tool to overcome critical section problem. Mutex is also a tool that is used to provide deadlock free mutual exclusion. It protects access to every critical data item, if the data is locked and is in use,it either waits for the thread to finish or awakened to release the lock from its inactive state.
Questions on embedded systems changes from company to company during interview , if you are preparing for any particular company for interview , please mail us at mail oureducation. Ask your queries about the embedded systems in the comment section below this article. I want to get job in embedded system. Please send me , on the embedded System course the conceptualquestions previous final exam paper ,From Derby University ,England. Can you provide me some sample questions and some topics which i should read.
These 36 solved Embedded Systems questions will help you prepare for technical interviews and online selection tests conducted during campus placement for freshers and job interviews for professionals. After reading these tricky Embedded Systems questions , you can easily attempt the objective type and multiple choice type questions on this topic. What is the need for an infinite loop in Embedded systems? How does combination of functions reduce memory requirements in embedded systems? The design philosophy of RISC architecture is such that only one instruction is performed on each machine cycle thus taking very less time and speeding up when compared to their CISC counterparts.
What is an embedded system? An embedded system is a special purpose computer system which is completely encapsulated by device it control. It is a programmed hardware device in which the hardware chip is programmed with specific function. It is a combination of hardware and software. What are the characteristics of embedded system?
Searching for another job can be so tedious that it can turn into a job itself. If you are expertise in with embedded development tools, debuggers and protocol analyzers then prepare well for the job interviews with to get your dream job. Here's our recommendation to prepare well for the job interview to achieve your career goals in an easy way.
So, there is a huge scope for professionals in the job market. We at Mindmajix, have prepared a bunch of top interview questions in this blog that covers the basics of the embedded systems.
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:. The usual way to mitigate this is to have the interrupt controller set a special variable which is observed by non-interrupt code, and which can then perform arbitrary actions.
This article is mainly focused on the most repeatedly asked embedded system interview questions. These embedded system questions not only for fresher but also good for the experienced person. I hope these embedded system interview questions with the answer will be helpful. If you have any other important questions relate to the embedded systems and concepts or want to give the answer to any mentioned embedded systems interview questions, then please write in the comment box. It is helpful to others.
Embedded Systems based Questions and Answers. What are the characteristics of embedded system?
Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся. Беккер изо всех сил цеплялся за жизнь. Мотоцикл, виляя, мчался по газону и, обогнув угол здания, выехал на шоссе. Халохот, кипя от злости, побежал к такси. Несколько мгновений спустя водитель уже лежал на земле, с изумлением глядя, как его машина исчезает в облаке пыли и выхлопных газов. ГЛАВА 82 Когда мысль о последствиях звонка Стратмора в службу безопасности дошла до сознания Грега Хейла, его окатила парализующая волна паники.
Он писал письма, отправлял их анонимному провайдеру, а несколько часов спустя этот провайдер присылал эти письма ему самому. Теперь, подумала Сьюзан, все встало на свои места. Танкадо хотел, чтобы Стратмор отследил и прочитал его электронную почту.
