With increasing hardware capabilities the demands on the functionality of user centric systems continuously expand. The next generation of automotive embed- ded systems is going to make use of multicore hardware architectures, which strongly enhances the computational power. This means a movement from concurrent to paral- lel computing. Although the competition for CPU time will decrease, other resources are not available in multiple instances. This raises the need for a management unit that controls access to resources other than the CPUs. Such a resource manager is able to utilise the capabilities of multicore hardware architectures for component based software systems more predictably. This paper builds a case for a resource sched- uler, identifies requirements and provides details of a prototype implementation. As an illustrative example, the domain of automotive multimedia/infotainment systems is used.
