XCPUScalar allows you to dynamically scale the processor speed of your handheld Pocket PC 2002, Windows Mobile 2003, WM2003 SE, and Windows Mobile 5. It uses the power of the XSCALE processor and unlocks its dynamic scaling capabilities. You can scale the processor speed from 100 to 728MHz. By scaling the processor speed down, you can increase the battery life between recharges or increase the speed when you need more power for playing games or multimedia programs that require more CPU power.
The speed can be scaled from 100 to 300MHZ on the fly for the iPaq 1910 ,100 to 500MHz for PXA250 XSCALE processors and 100 to 530MHz at 265MHz bus for PXA255, PXA26x, and 104 to 728MHz for PXA270, PXA27x or higher processors. Use the Auto Scaling capability of XCPUScalar and assign your own speeds to different CPU loads as shown in the picture above. With Auto Scaling, applications will get power on demand depending on CPU usage, saving battery life. Monitor CPU usage as you run your applications, XCPUScalar integrates with popular task managers like Wisbar, Icbar, and Gigabar. Monitor the health of your Pocket PC using the health meters. iPAQ 1910 users can almost double their framerates when watching movies or playing games.
PDA's based on XSCALE processors can enjoy speed increases of upto 30 to 35% (QUAKE timedemo1 test scores , reported 33 FPS using XCPUScalar on an Axim X30, on iPAQ 2215 is around 20 to 21 FPS. Speed will slightly vary from PDA to PDA. ).
