|
|
| The Dalvik virtual machine is the main application plat- form running on Googles Android operating system for mo- bile devices and tablets. It is a Java Virtual Machine run- ning a basic trace-based JIT compiler, unlike web browser JavaScript engines that usually run a combination of both method and trace-based JIT types. We developed a method- based JIT compiler based on the Low Level Virtual Machine framework that delivers performance improvement compa- rable to that of an Ahead-Of-Time compiler. We compared our method-based JIT against Dalviks own trace-based JIT using common benchmarks available in the Android Market. Our results show that our method-based JIT is better than a basic trace-based JIT, and that, by sharing profiling and compilation information among each other, a smart combi- nation of both JIT techniques can achieve a great perfor- mance gain. |
