Question

Which of the following can compute the exact number of clock cycles required to run an application?

(a) layout model

(b) coarse-grained model

(c) fine-grained model

(d) register-transaction model

I had been asked this question during an online interview.

This intriguing question originated from Risk and Dependability Analysis topic in portion Validation of Embedded Systems

Answer 1

Correct answer is (c) fine-grained model

To elaborate: The fine-grained model has the cycle-true instruction set simulation. In this modelling, it is possible to compute the exact number of clock cycles which is required to run an application.
