Scheduling of stream-based real-time applications for heterogeneous systems

Designers of mobile devices face the challenge of providing the user with more processing power while increasing battery life. Heterogeneous systems offer some opportunities to solve this challenge. In an heterogeneous system, multiple classes of processors with dynamic voltage and frequency scaling functionality are embedded in the mobile device. With such a system it is possible to maximize performance while minimizing power consumption if tasks are mapped to the class of processors where they execute the most efficiently.
