Earliest deadline first scheduling performs processor utilization up to 100 percent and improved robustness in overload situations. However, most automotive applications are running under static priority policy. Because of this, the standard operating system in the automotive industry, OSEK/VDX, just supports priority scheduling. This paper describes an EDF scheduler plug-in for OSEK/VDX. The plug-in provides EDF scheduling without changes to the operating system by delaying task activations.
