3. LongRun For A Long Run

To ensure a long battery life, the Crusoe processor comes equipped with 'LongRun' Dynamic Power Management. The frequency can change in steps of 33MHz, the voltage changes in steps of 25mV, and there are up to 200frequency/voltage changes per second possible. Sony has implemented a minimum performance of 300MHz @ 1.3V and a maximum performance of 600MHz @ 1.6V.

LongRun power management monitors the application's performance needs continuously and determines how much processor power is needed. The success of this can be seen later in the benchmark results.

Sony C1VN, C1VE And C1VJ

Enough of this theoretical stuff - let's jump to the reality of the Sony C1V-Series. There are different names for the same notebook depending on the territory.

The specifications are the same, but the software preload is different.
