Embedded Systems based Questions and Answers

Q1. What is an embedded system?

Ans. An embedded system is a special purpose computer system which is

completely encapsulated by device it controls. It is a programmed hardware device

in which the hardware chip is programmed with specific function. It is a combination

of hardware and software.

Q2.What are the characteristics of embedded system?

Ans. 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

Q3. What are the types of embedded system?

Ans. They are of 4 types

1. General computing

2. Control System

3. Signal Processing

4. Communication and network

Q4.What is digital signal controller ?

Ans. DSC is 16 bit RISC machine that combines control advantages of microcontroller and digital signal processing to produce tightly coupled single chip-single

instruction stream solution for embedded system design.

Q5. What are the components of embedded system?

Ans. Microcontroller, microprocessor, DSC, DSP, busses, system clock, Read only

Memory(ROM), RAM, Real time clock these are the components of embedded

system.

Q6. Why we use embedded systems?

Ans. 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.

Q7. What are the languages used in embedded system?

Ans. Assembly language and C are basically used for embedded system. Java and

ADA are also preferred.

Q8. How does combination of functions reduce memory requirement in

embedded system?

Ans. By using functions the amount of code that has to be dealt with is reduced thus redundancy is eliminated for everything common in function.
