Modélisation et Caractérisation d'une Plate-Forme SOC Hétérogène : Application à la Radio Logicielle.

Abstract : The work of this PhD has been carried out within the framework of the A3S project and relies on component aspects integrated within a SoC platform design methodology, which is based on the UML language. This methodology proposes a high-level design framework based on the A3S UML profile developed to provide real-time embedded system semantic especially in SDR domain. An MDA approach has been considered to deal with different abstraction levels when specifying systems.

First part of the work focused on identifying the component required designing a SoC system, and their characteristics depending on the component abstraction levels. Several types of component (software and hardware) whose characteristics depend on their modelling (PIM or PSM models) have been considered. Second part of the work focused on the definition of UML metamodels, which are grouped to define the A3S UML profile that establish the semantic of identified components depending on their modelling and their relations. We have defined extensive verification rules and applied a model of computation to inform designers about errors that have been done and to ensure the feasibility of their systems. Finally an operating system model has been included to demonstrate the scalability and the extension mechanisms of the UML language and profile which improve the list of components that have been already integrated within our framework. An UMTS application has validated our approach by comparing the estimated results computed by the tool with measured results obtained on a heterogeneous real-time platform (with several DSP and FPGA).
