The Dalvik Virtual Machine is a small, lightweight VM that allows your Java based applications to interface with the Android OS and hardware without overloading that set of slightly more limited hardware.
Myriad Group is now talking up their new Dalvik replacement, Dalvik Turbo. They are reporting a performance increase of “up to three times faster” and apparently reduced battery drain. It will work on all the major mobile platforms–ARM, MIPS, and Atom.
Look for more information on Dalvik Turbo during MWC, the Mobile World Congress.
