Component Assemblies in the Context of Manycore

We present a component-based software design flow for building parallel applications running on top of manycore platforms. The flow is based on the BIP - Behaviour, Interaction, Priority - component framework and its associated toolbox. It provides full support for modeling of application software, validation of its functional correctness, modeling and performance analysis on system-level models, code generation and deployment on target manycore platforms. The paper details some of the steps of the design flow. The design flow is illustrated through the modeling and deployment of two applications, the Cholesky factorization and the MJPEG decoding on MPARM, an ARM-based manycore platform. We emphasize the merits of the design flow, notably fast performance analysis as well as code generation and efficient deployment on manycore platforms.
