XCPUScalar 400 allows you to dynamically scale the processor speed of your handheld Pocket PC 2002.
It uses the power of the XSCALE processor and unlocks its dynamic scaling capabilities. You can reduce the speed of your handheld to 100MHz or increase its speed upto 472MHz.
By scaling the processor speed down, you can increase the battery live 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 472MHz.
