+      The <a href="freescale/">scripts</a> present:
+      </p>
+
+      <ul>
+       <li>an executable formalization of the operational semantics of
+           any <a href="http://www.freescale.com">Freescale</a>
+           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>
+       <li>a compiler from assembly language (pseudocodes + operands) to
+           machine code
+       <li>several automatic checks for unhandled opcodes, memory accesses,
+           correctness of ALU logic, etc.
+       <li>three examples of assembly programs (string reverse, counting sort
+           and perfect numbers sieve) with sets of data to run them
+      </ul>
+      </a>
+      
+      <p>The execution in the executable formalization has been compared
+         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>
+        in-circuit debugger.
+      </p>
+
+      <p>
+       The code (in <a href="http://caml.inria.fr">OCaml</a>)
+       of an executable <a href="freescale/freescale_ocaml">emulator</a>,
+       automatically generated from the scripts above. On the tests above,
+       it runs at about 29% of the speed of the
+       <a href="http://www.freescale.com/codewarrior">CodeWarrior</a>
+       emulation engine.
+      </p>
+
+      <p>The formalization has been the Undergraduate Thesis of
+         Mr. Cosimo Oliboni. The manuscript (italian only) can be found
+         <a href="http://matita.cs.unibo.it/documentation.shtml#freescale">
+         here</a>.
