The Hardware (HW)/Software (SW) partitioning/scheduling relies on two subtasks: the cost function and the real time (RT) analysis. Besides these two subtasks, the proposed generic framework, also called RT Design Trotter (RTDT), processes the problem of the Quality of Service (QoS) management. The aim is to add a new dimensions to solution selection, namely the guarantee of QoS from both application quality and RT issue points of view. The proposed framework defines an iteration loop of three steps that solve the sub-problems. The cost function takes into account the System on a Chip (SoC) area and the static and dynamic power dissipation. We show how our tool can be used to rapidly evaluate the impact of the application quality and the RT constraints choices (QoS parameters) over the final cost.
