Hardware, Embedded Systems "The name Snapdragon is fast becoming well-known among consumers as the chip to have inside your smartphone. Offering speeds of up to 1.5GHz at the moment, it's certainly one of the fastest mobile chips out there. Qualcomm doesn't want the reputation of Snapdragon to falter, though, so the chip manufacturer has just announced an update that will have smartphone and tablet users drooling. The next iteration of the Snapdragon processor line is codenamed Krait and uses 28nm manufacturing technology. It will be offered in single, dual, and quad-core versions with clock speeds up to 2.5GHz. If the huge increase in performance wasn’t enough for you, Qualcomm also boast a 65% reduction in power use over existing mobile ARM chips."

Exactly the opposite. With a VM you can do code validation as the verifiers present in the JVM and CLR attest to.

You cannot so easily do code validation with assembly, because of the lower level of allowed operations.

That is the main reason why Google is forced to restrict the NaCL instruction set.

Plus thanks to dynamic code profiling, it is possible to have a JIT generate better code for the actual running processor, as a static compiler would be able to.
