OSEK/VDX is a standard&#151or rather a set of standards&#151which emerged from the European automotive industry. First there was OSEK [an acronym in German which translates to Open Systems and the Corresponding Interfaces for Automotive Electronics], developed by the German companies. Then there was VDX [Vehicle Distributed eXecutive], produced by their French counterparts. These two standards were combined in the mid-1990s to form OSEK/VDX, which is gaining very wide acceptance around the world. It is normally referred to as just OSEK. OSEK consists of three main standards, which cover the operating system [OS], inter-process and inter-processor communication [COM] and network management [NM]. These will all be outlined in this paper, but a detailed study of the APIs is not included.
