Version January 23, This document is an official release and replaces all previously distributed documents. The OSEK group retains the right to make changes to this document without notice and does not accept any liability for errors.
It aims at an industry standard for an open-ended architecture for distributed control units in vehicles. This document describes the OIL concept for the description for the OSEK real-time systems, capable of multitasking and communications, which can be used for motor vehicles.
It is not a product description that relates to a specific implementation. For a better understanding of this document, the reader should be familiar with the contents of these other specifications.
The OIL description may be hand-written or generated by a system configuration tool. Sub-systems delivered in source code are compiled together with the application; others delivered as a library are integrated by the linker.
OIL defines standard types for its objects. Each object is described by a set of attributes and references. Each OSEK implementation can define additional implementation-specific attributes and references.
It is possible only to add attributes to existing OIL objects. Creating new OIL objects, or other changes to the grammar, are not allowed. All non-standard attributes optional attributes are considered to be fully implementation-specific and have no standard interpretation. Each OSEK implementation can limit the given set of values for attributes e.
Description of the OIL objects: IPDUs carry messages used in external communication. All keywords, attributes, object names, and other identifiers are case-sensitive. It contains an OIL-internal extension in syntax and semantics.
It is not backwards compatible with OIL version "2.
Two OIL sets of objects and standard attributes are defined: OS and full featured COM, supporting the conformance classes: OS with internal communication only, supporting the conformance classes: The implementation definition must be present in the OIL description and must contain all standard attributes, which are listed in section 3.
The value range of those attributes may be restricted. Attribute definition is described in chapter 4. Additional attributes and their properties can be defined for the objects for a particular OSEK implementation.You just clipped your first slide!

Daemon Task Startup Hook The RTOS daemon task is the same as the Timer Service timberdesignmag.commes it is referred to as the daemon task because the task is now used for more than just servicing timers.
The OSEK/VDX consortium provides the OIL language (OSEK Implementation Lan- guage) as a standard conﬁguration language, which is used for the static deﬁnition of the RTOS objects which are instantiated and used by the application.
OSEKBuilder is responsible for generating the header and configuration files used to build OSEK. If it doesn't run properly, you get a mangled OSEK image. Another thing to check is the preprocessor output to ensure that the task data structures (as generated by OSEKBuilder) are present.

The specification of the OSEK operating system is to represent a uniform environment which supports efficient utilisation of resources for automotive control unit application software. The OSEK operating system is a single .
