There is no single doc other that the source, but lots of bits and pieces 
scattered thru clp archives.  The CPython interpreter, tokenizes, parses, 
and compiles Python to CPython bytecode.  The library manual chapter on the 
dis module defines the stack-based CPython virtual machine.  The bytecode 
is interpreted in a loop with a giant switch (ceval.c).  Python objects 
have a common header and a type-specific value section.  For builtin type 
objects, the value section is a standard set of slots for functions 
corresponding to the various operators and builtins.  For more, see the 
source or persistently search Google's archive for the group.
