Re: Embedded systems Anna university question bank

For Embedded systems the Anna University is provides question bank for old question papers.

An embedded system is a programmed controlling and operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.


Embedded systems Anna university question bank:


UNIT-I
INTRODUCTION TO EMBEDDED SYSTEMS
Part - A (2 MARKS)
1. Define a System.
A way of doing one or more tasks according to a program.

2. What is an embedded system?
An embedded system employs a combination of hardware & software (a "computational engine") to perform a specific function; is part of a larger system that may not be a "computer"; works in a reactive and time-constrained environment

3. What are the typical characteristics of an embedded system?
Typical characteristics:
Perform a single or tightly knit set of functions;
Increasingly high-performance & real-time constrained;
Power, cost and reliability are often important attributes
That influence design;
Application specific processor design can be a significant component of some embedded
systems.
Other characteristics:
Application specific
Digital signal processing in ECS
Reactive
Real-time
Distributed

4. What are the advantages of embedded system?
Advantages:
Customization yields lower area, power, cost, etc.,

5. What are the disadvantages of embedded system?
Disadvantages:
Higher HW/software development overhead design, compilers, debuggers, etc., may result in delayed time to market!

6. What are the applications of an embedded system? Embedded Systems: Applications:
Consumer electronics, e.g., cameras, camcorders, etc.,
Consumer products, e.g., washers, microwave ovens, etc.,
Automobiles (anti-lock braking, engine control, etc.,)
Industrial process controllers & avionics/defense applications
Computer/Communication products, e.g., printers, FAX machines, etc.,
Emerging multimedia applications & consumer electronics

7. What are the various embedded system designs Modeling Refining (or "partitioning") HW-SW partitioning

8. What are the complicating factors in embedded design?
Complicating factors in the design of embedded systems
Many of the subtasks in design are intertwined.
Allocation depends on the partitioning, and scheduling presumes a certain allocation.
Predicting the time for implementing the modules in hardware or software is not very easy, particularly for tasks that have not been performed before.

9. What are the real-time requirements of an embedded system?

10. What are the functional requirements of embedded system?
Data Collection
Sensor requirements
Signal conditioning
Alarm monitoring Direct Digital Control
Actuators Man-Machine Interaction
informs the operator of the current state of the controlled object
assists the operator in controlling the system.

11. What are the main components of an embedded system?
Three main components of embedded systems:
1. The Hardware
2. Application Software
3. RTOS

12. Define embedded microcontroller.
An embedded microcontroller is particularly suited for embedded applications to perform dedicated task or operation.
Example: 68HC11xx, 8051, PIC, 16F877, etc.,
