ARM Energy Probe
Software is ultimately responsible for energy efficiency
The ARM processor processor technology stands out due to the indisputable energy efficiency. Between the processor itself and the final product shipping, many things can dramatically impact on energy consumption. The software can mke all the difference concerning the power consumption In this respect.
When using DS-5 with the Streamline performance analysis, the ARM Energy probe can assist in the optimization of the software. In this combination Streamline can acquire real power data from your board and correlate it with all the other software and hardware statistics, including DVFS and cpuidle, to show you the true picture of your power management. Alternatively, Streamline can read and display these measurements directly from your Linux hwmon subsystem.
