Have you read "The Technology Behind Crusoe Processor" by Alexander
Klaiber
(http://www.transmeta.com/pdf/white_papers/paper_aklaiber_19jan00.pdf)?
This is an EXCELLENT general introduction to binary compilation and
"Code Morphing" software.


Transmeta's patents (especially US06031992), although somewhat wordy,
has a lot of useful information (not only about "Code Morphing" but
also on binary compilation in general).


There are also special issues of "IEEE Computer"
(http://computer.org/computer/co2000/r3toc.htm) and "IEEE Transaction
on Computers" (http://computer.org/tc/tc2001/t6toc.htm).


Hope that helps.

P.S.: Java just-in-time compilers and binary compilers, although have
many similarities, also have many differences. To be successful, any
binary compiler have to rely on strong hardware support, and hence
processors and binary compilers usually developed simultaneously. It
means that articles about Java JIT's have only limited usefulness for
your purposes.
