The ever increasing intricacy of the systems and the increasing use of reconfigurble heterogeneous devices significantly enlarges the design complexity of the modern embedded systems. As a result, to create a good design, it is essential to perform Design Space Exploration( DSE) at various design levels in order to evaluate several design choices. DSE at early design stages helps designers to systematically explore trade-offs between various design goals and to make various design decisions such as hardware/software partitioning, architecture - to - application mappings, task scheduling and task allocation, performance evaluation etc. As the design progresses, the design space can be gradually trimmed and pruned at different design levels of unsuitable design alternatives until a final optimal solution is reached. In this work, we present a system level framework for higher level runtime design space exploration of reconfigurable architectures.
