Targeting Reconfigurable FPGA based SoCs using the MARTE UML profile: from high abstraction levels to code generation

Abstract

International audienceAs SoC design complexity is escalating to new heights, there is a critical need to find adequate approaches and tools to handle SoC co-design aspects. Additionally, modern reconfigurable SoCs offer advantages over classical SoCs as they integrate adaptivity features to cope with mutable design requirements and environment needs. This paper presents a novel approach to address system adaptivity and reconfigurability. A generic model of reactive control is presented in a SoC codesign framework: Gaspard. Afterwards, control integration at different levels of the framework is illustrated for both functional specification and FPGA synthesis. The presented work is based on Model-Driven Engineering and the UML MARTE profile proposed by Object Management Group, for modeling and analysis of real-time embedded systems. The paper thus presents a complete design flow to move from high level MARTE models to code generation, for implementation of dynamically reconfigurable SoCs
