Abstract :
The hardware (HW)/software (SW) partitioning 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 of this paper is to add a new dimension to solution selection, namely the guarantee of QoS from both application and RT 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 chip (SoC) area and the static and dynamic power dissipation. We show how our tool can be used to rapidly evaluate the impact of application quality and RT constraints choices (QoS parameters) over the final cost.
