I made a presentation for our research group about Just-In-Time (JIT)
compilation last fall. The slides from the presentation are available
at http://www.eb.uah.edu/~cohen/javanauts/jit1/index.html. It is
meant as an introduction to the subject and does not go into great
detail.


You might broaden your search and look at the binary-to-binary
translators, e.g. FX!32 (i86->alpha)
(http://www.digital.com/DTJP01/DTJP01HM.HTM) by DEC and Embra
(http://www-flash.stanford.edu/Embra/). Many of the techniques used in
these binary-to-binary translators are applicable to generating
high-performance Java Virtual Machines.


On a 8051 you might be a bit tight on space to implement a JIT
(assuming a 16-bit address space). Good luck.
