BASEMENT - A DISTRIBUTED REAL-TIME ARCHITECTURE FOR VEHICLE APPLICATIONS

This paper presents BASEMENT(TM), a distributed real-time architecture developed for vehicle internal use in the automotive industry. The Ba sement concept is holistic, in the sense that it covers application de velopment as well as the hardware and software that provide execution and communication support. The key constituents of the concept are res ource sharing (multiplexing) of processing and communication resources a guaranteed real-time service for safety critical applications a bes t-effort service for non-safety critical applications a communication infrastructure providing efficient communication between distributed d evices a program development methodology allowing resource independent and application oriented development of application software. A real- time kernel has been developed together with two design tools: a syste m simulator and an off-line scheduler. System development is illustrat ed by presenting an Intelligent Cruise Control application. BASEMENT i s a registered trademark of Mecel AB.
