| Creditcard-sized XScale SBC boasts extensive embedded Linux support |
Aug. 18, 2003
 InHand Electronics Inc. announced immediate availability of the third generation of its tiny "Fingertip" single-board computer family. The credit card sized Fingertip3 is InHand's first SBC to be based on an Intel XScale microprocessor, and also provides substantially enhanced power management capabilities and an SD Card slot. The board supports embedded Linux as its target operating system.
According to InHand CEO Andrew Girson, the new SBC provides a range of power management capabilities, including enhancements to measure and adjust the CPU's core operating voltage on-the-fly and optional support for an ultra-low-power mobile memory architecture. Additionally, the board supports InHand's "BatterySmart" system software suite, which leverages the XScale processor's dynamic performance monitoring capabilities and includes features such as an improved real-time dynamic clock-scaling algorithm, reduced power peripheral software drivers, and additional measurement and analysis tools, Girson said. Combining the BatterySmart software with low-voltage memory, Fingertip3's idle-mode power consumption is 50 percent lower than the previous StrongARM-based Fingertip SBC, he added.
