De occam para o transputer: compilação via reescrita de termos
Renata Spencer, Augusto C. A. Sampaio · 1996
The aim of this work is the development of a prototype compiler from occam to the transputer, in such a way that the correctness of the compiler is ensured by construction. The method used reduces the source program, through a series of algebraic transformations, to a normal form which can be directly mapped into the instructions of the target machine. Using the term rewriting facilities provided by OBJ3, the correctness proof gives as a byproduct a compiler prototype, so that at the end of the process, a running prototype will be available. This compilation method was already available, and its application was illustrated for a very simple language; our purpose here is to extend the method to deal with realistic languages and machines, such as occam and the transputer.
