Synchronous protocol for real-time communications in intelligent vehicle

In this paper we describe the design and implementation of a real-time distributed executive for an obstacles detection system, PRO-CHIP, using synchronous communication protocol. The synchronous protocol permits to preserve the consistency specification of the application algorithms. The executive model is based on generic executive kernel which contains a portable set of services (high level system) and very fast microkernel (low level system) which manages concurrent processes and schedules their execution. This executive provides the maximum portability, preserves the efficiency of the system, and guarantees real-time constraints.
