•Features including the speed of the processor.

•Battery back-up

•Operating System

A good Operating system can make an efficient use of the system's hardware resources but is more driven by the software applications that you wish to run. However, the first two are directly influenced by the design methodology and the technology node that goes behind designing your device.

You would love to buy a cell-phone with a faster processor to enable you to have your applications run fast, your computations quicker. Also, you wouldn't want to charge your cell-phone every hour. Or for that matter everyday! This would translate into a design challenge to have your device to consume least power.

Frequency and power go hand-in-hand. You cannot just go on increasing the frequency (assuming that timing is met!), without expecting any hit on power.

Before I conclude this post, I would like to make one last point.

The above table shows the trend of ever-increasing power dissipation with scaling down of technology nodes. This has forced the designers to come up with innovative design solutions to deliver the best to you.

In upcoming posts, we will discuss these design-for-low-power solutions in detail
