A bi-constraints adaptation technique for embedded multimedia systems

摘要

The growing number of complex multimedia applications has raised new challenges in the design of embedded mobile multimedia systems. These systems must be able to react to resource limitations and external environment fluctuations to meet applications' timing constraints and provide an acceptable service. In this paper, we present a new adaptation technique enabling a multi-task system to adapt to variations in both processor-load and network bandwidth resources. Adaptations are performed by dynamically reconfiguring the running applications to meet shared resource allocations using a new resource sharing algorithm. Tests were done on the H.264/AVC video compression application.
