Optimization of Real Time Application on Mixed Architecture Using AAA Methodology Extension.

Mixed Architectures contain programmable devices and reconfigurable devices. They provide a powerfull answer to meet the computational requirement of latest digital signal processing applications. But the complexity of the corresponding algorithms and the multiplicity and diversity of computing components usually lead to a huge number of possible implementations. Architecture Algorithm Adequation (AAA) is one of the rapid prototyping methodologies which allow to explore the solution set to build an optimized application. However, it requires improvement in order to support mixed architectures containing both programmable and configurable components. This paper suggests an extension of the AAA methodology to support mixed architectures. The AAA architecture model is first extended to mixed architecture. Then, we present the coupling of existing tools (SynDEx and SynDEx-IC) in order to support mixed architectures. Finally a communication IP is proposed to manage FPGA communication and its synchronization with other components of the mixed architecture.
