HW/SW Interface Impact on an Adaptive Multimedia System Performance: Case study

The embedded systems are more and more complex. They must answer to contradictory constraints. Indeed, these systems integrate new functionalities that require high performance architectures. At the same time, these systems must be flexible and adaptive since they work in a fluctuating environment and have a quite unpredictable workload. In order to answer to all these constraints, we propose a new adaptive system that can adjust its performances according to the context. We are interesting in studying architectural adaptation technique in a reconfigurable platform. We focus in hardware/software interface impact on the system performance. A case study for the application "3D synthesis" is carried out.
