iPhone CPU Java Support
The ARM processor found inside the iPhone includes special features for accelerating Java code, a study of the chip reveals. The chip is likely to be the Samsung-made S3C6400 and therefore supports the Jazelle engine, which reduces memory use to a fraction of what would be needed for software and uses a virtual engine that juggles multiple Java programs at once without a major drop in performance. Phones can use this to easily load chat and games without requiring more expensive hardware, the ARM group says.
