29        <li>an executable formalization of the operational semantics of
30            any <a href="http://www.freescale.com">Freescale</a>
31            micro-controller of the <a href="http://www.freescale.com/webapp/sps/site/homepage.jsp?nodeId=0162468449&tid=FSH">HC05/HC08/RS08/HCS08 families</a>
32        <li>a compiler from assembly language (pseudocodes + operands) to
33            machine code
34        <li>several automatic checks for unhandled opcodes, memory accesses,
35            correctness of ALU logic, etc.
36        <li>three examples of assembly programs (string reverse, counting sort
37            and perfect numbers sieve) with sets of data to run them
38       </ul>

41       <p>The execution in the executable formalization has been compared
42          to real world execution using the <a href="http://www.freescale.com/webapp/sps/site/overview.jsp?code=784_LPBBNEWTOOL&fsrch=1">USB SPYDER08</a>

47        The code (in <a href="http://caml.inria.fr">OCaml</a>)
48        of an executable <a href="freescale/freescale_ocaml">emulator</a>,
49        automatically generated from the scripts above. On the tests above,
50        it runs at about 29% of the speed of the
51        <a href="http://www.freescale.com/codewarrior">CodeWarrior</a>
