Abstract
This paper presents a system for application scheduling, binding and routing for a run-time reconfigurable operator based multimedia architecture (ROMA).We use constraint programming to formalize our architecture model together with a specific application program. For this purpose we use an abstract representation of our architecture, which models memories, reconfigurable operator cells and communication networks.We also model network topology. The use of constraints programming makes it possible to model the application scheduling, binding and routing as well as architectural and temporal constraints in a single model and solve it simultaneously. We have used several multimedia applications from the Mediabench set to evaluate our system. In 78% of cases, our system provides results that are proved optimal.

Hardware/Software Co-Design of H.264/AVC Encoders for Multi-Core Embedded Systems

Abstract
This paper presents a multi-core H.264/AVC encoder suitable for implementations in small and medium complexity embedded systems. The proposed structure results from an efficient hardware/software co-design methodology, where the encoder software application is highly optimized and structured in a very modular and efficient manner, so as to allow its most complex and time consuming operations to be offloaded to dedicated hardware accelerators. The considered methodology adopts a simple and efficient core interconnection mechanism to easily allow the inclusion and the removal of such optimized processing cores. Experimental results obtained with the implementation in a Virtex4 FPGA of an H.264/AVC encoder using an ASIP IP core as a ME hardware accelerator have proven the advantages of this methodology. For the considered system, speedup factors greater than 15 were obtained with a very modest increase of the involved hardware resources.
