A small hybrid JIT for embedded systems
Geetha Manjunath, Venkatesh Krishnan · ACM SIGPLAN Notices · 2000
Just-In-Time (JIT) Compilation is a technology used to improve speed of virtual machines that support dynamic loading of applications. It is better known as a technique that accelerates Java programs. Current JIT compilers are either huge in size or compile complete methods of the application requiring large amounts of memory for their functioning. This has made Java Virtual Machines for embedded systems devoid of JIT compilers. This paper explains a simple technique of combining interpretation with compilation to get a hybrid interpretation strategy. It also describes a new code generation technique that works using its self-code. The combination gives a JIT compiler that is very small (10K) and suitable for Java Virtual Machines for embedded systems.
