Implementation of a CAN Controller and Monitor Application on the Rapid Prototyping Platform REAR

. Rapid Prototyping is used in embedded systems design as a means to reduce development time and costs. At an early stage in the development cycle, the specification is implemented in a working protoype, which can be used to test the specification and, in real-time systems, also the timing constraints. The REAR Rapid Prototyping Environment was built as an adaptable target platform for embedded real-time systems. It supports both the proof that the system meets all its deadlines, and the automated translation of a system specification into an executable prototype. This paper presents a CAN controller and monitor application, which was implemented and evaluated on REAR as a first non--trivial real--world application with a wide range of timing and coordination requirements towards the target architecture.
