Abstract

This paper shows how to compile a program written in a subset of occam into a normal form suitable for further processing into a netlist of components which may be loaded into a Field-Programmable Gate Array (FPGA). A simple state-machine model is adopted for specifying the behaviour of a synchronous circuit where the observable includes the state of the control path and the data path of the circuit. We identify the behaviour of a circuit with a program consisting of a very restricted subset of occam. Algebraic laws are used to facilitate the transformation from a program into a normal form. The compiling specification is presented as a set of theorems that must be proved correct with respect to these laws. A rapid prototype compiler in the form of a logic program may be implemented from these theorems.
