Lightspeed Extends Device Overclocking Support
A new beta version of Lightspeed has been announced. The utility enables many Palm OS 5 handheld processors to be overclocked or underclock. The new version is now compatible with Intel XScale, TI OMAP, and Motorola i.MXL processors.
Lightspeed is an application that lets the user change the CPU clock frequency and the of supported Palm OS 5 devices. Version 2.0 adds support for 12 more handhelds equipped with Texas Instruments OMAP and Motorola i.MX1/i.MXL processors. Newly supported devices include:
TI OMAP devices:
- PalmOne Tungsten T
- PalmOne Tungsten T2
- PalmOne Tungsten E
- PalmOne Zire 21
- PalmOne Zire 71
Motorola i.MX1/i.MXL devices:
- Sony CLIE TJ25
- Sony CLIE TJ35
- Sony CLIE TJ27
- Sony CLIE TJ37
- Garmin iQue 3600
- Tapwave Zodiac 1/2
With OMAP processors that normally run between 126 MHz or 144 Mhz, the CPU speed can be set as low as 3 Mhz to extend the battery life and as high as 192 Mhz to improve performance and user experience. Motorola Chips can range from 50 Mhz to 230 Mhz.
The developers have also created a new API that 3rd party developers can make use off. The Lightspeed developer API makes it possible for other developers to change the CPU speed from inside their applications. They can set the CPU speed high when performing lengthy processor intensive operations and set the CPU speed low when performing less processor intensive operations which helps improve the user experience and extend battery life.
