The BitsyXb is an embedded single board computer that leverages the power and speed of the Marvell® PXA270 processor while maintaining low power and a small form factor.
Eurotech systems have been successfully deployed in several battery-backed embedded applications including PDA/handheld, instrumentation, medical monitoring, telematics, and several others.
Customization
The BitsyXb can be used as a stand-alone single board computer or can be integrated with a standard or custom adapter board for further feature expansions, including Power over Ethernet.
The BitsyXb is designed as low-cost, application-ready platform that can reduce the product-to-market cycle from years to several months.
The BitsyXb provides dynamic (variable) speed, voltage regulation, and includes 5 low power modes which Eurotech applies in low level software code to make BitsyXb power-stingy and perfect for handheld, wearable, and unmanned applications.

Video Performance Comparison. PXA and IMX Processors for Various CODECs - White_Papers
Media for small, embedded devices is in our future. We ran some quick tests on the leading PXA (Marvell) and i.MX (Freescale) CPU architectures to see where the current and likely future price/performance leader is. The operating system, across the board, was Windows CE. We ran the same media file, compressed four different ways, on three CPUs with three different media players. Performance differences of greater than two to one were seen; however these differences are small compared to the potential effect of application-specific features that exist with these highly specialized CPUs.
