Question

The number of times a fetch from memory is performed per output sample is one of the factor used in the implementation of the system.

(a) True

(b) False

I have been asked this question by my college professor while I was bunking the class.

My doubt is from Structures for Realization of Discrete Time Systems topic in chapter Discrete Time Systems Implementation of Digital Signal Processing

Answer 1

Right option is (a) True

Easiest explanation: According to the recent developments in the design and fabrication of rather sophisticated programmable DSPs, other factors, such as the number of times a fetch from memory is performed or the number of times a comparison between two numbers is performed per output sample, have become important in assessing the computational complexity of a given realization of a system.
