Abstract Scalability of architecture, programming model and task control management will be a major challenge for future VLSI systems. In this context, homogeneous MPSOC is a seducing approach,as it ,is intrinsically scalable. ,HS-Scale is a contribution in this ,domain ,and ,was ,already published ,in [1,2]. In this article, we present an original MPI-based adaptive task migration support for the HS-Scale system. Our previous communication,API was modified in order to be MPI compliant. In order ,to enable ,task migration ,without any MMU, a Position Independent Code compilation technique is implemented. The self-adaptability is ,based ,on monitoring information collected at run-time by each,processing element (PE). Each PE is endowed,with the same decisional capability insuring the scalability of the solution. A MJPEG case study validated on a,multi-FPGA prototyping platform is presented. The observation of the ,dynamic ,behavior ,of HS-Scale shows that the system is able ,to find itself a stable ,task placement providing,the ,best performance ,in terms ,of processing throughput.
