dynamic translation
     
         A {virtual machine} implementation approach,
        used to speed up execution of {byte-code} programs.  To
        execute a program unit such as a {method} or a {function}, the
        virtual machine compiles its bytecodes into (hardware) machine
        code.  The translated code is also placed in a cache, so that
        next time that unit's machine code can be executed
        immediately, without repeating the translation.
     
        This technique was pioneered by the commercial {Smalltalk}
        implementation currently known as {VisualWorks}, in the early
        1980s.  Currently it is also used by some implementations of
        the {Java Virtual Machine} under the name {JIT} (Just In Time
        compilation).
