Test: Introduction of Interrupts - Question 1

The time taken to respond to an interrupt is known as

Detailed Solution for Test: Introduction of Interrupts - Question 1

Explanation: The interrupts are the most important function of the embedded system and are responsible for many problems while debugging the system. The time taken to respond to an interrupt is called the interrupt latency.

Test: Introduction of Interrupts - Question 2

 Into how many parts does the interrupt can split the software?

Detailed Solution for Test: Introduction of Interrupts - Question 2

Explanation: The software interrupt can split into two parts. These are foreground work and background work.

Test: Introduction of Interrupts - Question 3

Which of the following allows the splitting of the software?

Detailed Solution for Test: Introduction of Interrupts - Question 3

Explanation: The interrupt can make the software into two main parts and these are foreground work and background work.

Test: Introduction of Interrupts - Question 4

 Which part of the software is transparent to the interrupt mechanism?

Detailed Solution for Test: Introduction of Interrupts - Question 4

Explanation: The interrupt mechanism is transparent to the background software, that is, the background software is not aware of the existence of the foreground software.

Test: Introduction of Interrupts - Question 5

 Which part of the software performs tasks in response to the interrupts?

Detailed Solution for Test: Introduction of Interrupts - Question 5

Explanation: In the foreground work, the tasks are performed in response to the interrupts but in the background work, the tasks are performed while waiting for an interrupt.

Test: Introduction of Interrupts - Question 6

 Which factor depends on the number of times of polling the port while executing the task?

Detailed Solution for Test: Introduction of Interrupts - Question 6

Explanation: The data transfer rate can determine the number of times the port is polled while executing the task.

Test: Introduction of Interrupts - Question 7

 In which of the following method does the code is written in a straight sequence?

Detailed Solution for Test: Introduction of Interrupts - Question 7

Explanation: In the spaghetti method, the code is written in a straight sequence in which the analysis software goes and polls the port to see if there is data.

Test: Introduction of Interrupts - Question 8

Which of the following can improve the quality and the structure of a code?

Detailed Solution for Test: Introduction of Interrupts - Question 8

Explanation: The subroutine can improve the quality and the structure of the code. By using the polling method, as the complexity increases the software structure rapidly fall and it will become inefficient. So the subroutine method is adopted.

Test: Introduction of Interrupts - Question 9

 Which of the following can be used to create time-driven systems?

Detailed Solution for Test: Introduction of Interrupts - Question 9

Explanation: The interrupts which are asynchronous can be used with systems that are the event as opposed to the time driven.

Test: Introduction of Interrupts - Question 10

What does ISR stand for?

Detailed Solution for Test: Introduction of Interrupts - Question 10

Explanation: The data transfer codes are written as part of the interrupt service routine which is associated with the interrupt generation by the hardware.
