The Need for Speed - D-PHYOn the Move - Hezi SaarJul. 30, 2012 |
I cover topics about low power and mobile applications in the past years but there is something that is often neglected. It comes at the expense of lowering the power and it is performance. We can argue that minimizing power consumption is dependent on what kind of power we’re reducing (for example static or leakage vs. dynamic power) and its effect of the performance but we know that there is no void in physics and Higher Voltage threshold for example reduces leakgae but affects max performance.
The problem we have is that as much as we need lower leakage power and lower dynamic power to prolonge the battery life between charges, we also need high performance as we don’t want to wait for an application to load itself or transfer data to our mobile device.
