%X This paper summarises the results of the realisation of a
   Cruise Control system in occam using an implementation of
   the Kent Retargettable occam Compiler (KRoC) on the Philips
   8051 microcontroller. The increase in complexity of systems
   designed comes with difficulties that can probably be
   overcome using concurrent programming languages. occam is
   such a language, originally developed for use with
   transputers. The KRoC initiative allows one to translate the
   transputer assembly produced from a program written in occam
   into the assembly of another processor. In this case, it was
   implemented for the Philips 8051 microcontroller, which is
   an 8\-bits processor. The design and realisation in occam of
   the Cruise Control system of Yourdon demonstrate its proper
   functioning. The generated code is tested using a real\-time
   in\-circuit 8051 emulator and special hardware to represent
   car and interface. The design process using occam is
   compared to a regular solution using a language like C.
   Since this port is the first of its kind inasmuch as it is
   not targeting \[rs]large\[rs] processors like the SPARC,
   important conclusions can be drawn regarding the power of
   the CSP\-concept. The port is not complete yet, future work
   on it is recommended.
