Question

If ‘n’ denotes the number of clock cycles and ‘T’ denotes period of the clock at which the microprocessor is running, then the duration of execution of loop once can be denoted by

(a) n+T

(b) n-T

(c) n*T

(d) n/T

This question was addressed to me in an internship interview.

This is a very interesting question from Timings and Delays in section Special Architectural Features and Related Programming of Microprocessor

Answer 1

Correct option is (c) n*T

To elaborate: The duration of execution of the loop is the product of number of clock cycles and the period of the clock cycle at which microprocessor is running.
