Future generations of mobile phones, including advanced video and digital communication layers, represent a great challenge in terms of real-time embedded systems. Program-mable multicomponent architectures may provide suitable target solutions combining flexibility and computation po-wer. The aim of our work is to develop a fast and automatic prototyping methodology dedicated to signal processing ap-plication implementation on parallel heterogeneous architec-tures, two major features required by future systems. This paper aims to present the Algorithm Architecture Adequa-tion methodology from both the description of application and multicomponent architecture to the dedicated real-time distributed executives. Then a comparison is done between executives which use or not a resident Real-Time Operating System. This work is finally illustrated by the execution of a multimedia application based on a scalable LAR video codec. 1.
