PXA Clocker is an application that allows you to change system frequency for Palm OS5-driven PDAs that use Intel PXA processors. The list of supported devices includes Sony Clie, PalmOne Zire 72, Zire 31, Tungsten C, T3, T5, E2 and LifeDrive devices.
PXA Clocker was debuted in August 2003 as proof of concept application to demonstrate how to change system frequencies for PXA-based devices. It was the first clock management application for Intel PXA processors. PXA Clocker 1.0 worked with Sony Clie devices. A couple of months later we added support for Palm Tungsten platform. Again, before anyone else. Later we added support for PXA270 processors. Guess what? We did it first again!
PXA Clocker allows you to either increase system frequency (up to 230% on some models), boosting performance of complex applications or decrease system frequency to a minimum available setting of 100MHz, allowing you to preserve precious battery power.
Additionally, PXA Clocker has an ability to turn off clock frequencies for unused peripherals, which also extends battery life.
All settings can be changed either globally or per-application. PXA Clocker includes support for applications on memory cards, and for shortcut management applications, such as PowerRun.
