About Dalvik of Android Virtual Machine

One of the primary differences between Dalvik and the standard Java Virtual Machine (JVM) Is that Dalvik is based on registers while JVM is based on stacks. Some people have been guessing that the register-based method is chosen because it provides better support for Advance Optimization (ahead-of-time optimization, this is quite helpful for a restricted environment like mobile phones.

Another major difference between Dalvik and Java is the runtime environment-Dalvik is optimized to allow running instances of multiple virtual machines in limited memory at the same time, each Dalvik application is executed as an independent Linux Process.

Every Android appProgramThey all run in their own processes and all have an independent Dalvik Virtual Machine instance. Every DVM is a process in Linux, so it can be considered the same concept.
