just-in-time ==>
dynamic translation
<architecture> 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).
