Question

Which of the following is an important ingredient of all power optimization?

(a) energy model

(b) power model

(c) watt model

(d) power compiler

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

My enquiry is from Compilers in portion Implementing Embedded System: Hardware/Software Codesign of Embedded Systems

Answer 1

Right choice is (b) power model

The explanation is: Saving energy can be done at any stage of the embedded system development. The high-level optimization techniques can reduce power consumption and similarly compiler optimization also can reduce the power consumption and the most important thing in power optimization are the power model.
