Just In Time compiler
JVM
contains both Interpreter and JIT compiler both are
combindely used for converting byte code to machine
language instruction
Overview
Java(tm) is one of the most dominant programming languages,
and used for a wide range of applications including games
and pervasive devices and mission-critical e-business
applications. A Java program is compiled into an
intermediate language called bytecodes, and it can be
downloaded through the network and executed on any
computers that have Java execution environment. However,
the overhead for interpreting bytecodes is a serious
bottleneck.
We have been researching and developing various techniques
for the Java Just-In-Time Compiler, which allows much
faster execution by compiling bytecodes into native machine
code on the fly. Our JIT compiler is used on almost all
Java platforms of IBM, ranging from network computers (NC)
to mainframes.
