Using RTOS in the AAA methodology automatic executive generation

Future generations of mobile phones, including advanced video and digital communication layers, represent a great challenge in terms of real-time embedded systems. Programmable multicomponent architectures may provide suitable target solutions combining flexibility and computation power. The aim of our work is to develop a fast and automatic prototyping methodology dedicated to signal processing application implementation on parallel heterogeneous architectures, two major features required by future systems. This paper aims to present the Algorithm Architecture Adequation 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.
