FlexTiles: A globally homogeneous but locally heterogeneous manycore architecture

Résumé

This paper introduces the FlexTiles platform, which consist of a manycore architecture associated with a complete tool ow. The di erent components of the manycore architecture are based on general purpose processors (GPP), low power DSP cores and an eFPGA on which dedicated IPs can be dynamically con gured at run-time. Thus, in order to mask the underlying heterogeneity of such an architecture, innovative software mechanism and hardware interface were de ned. These features enable a breakthrough in term of computing performance while improving the on-line adaptive capabilities. Given the large variety of possible use cases that these platforms must support and the resulting workload variability, o ine approaches are no longer su cient because they do not allow coping with time changing workloads. In order to facilitate the architecture adaptation under di erent scenarios, a programming model that considers both static and dynamic behaviors is proposed. The proposed architecture has been implemented on a FPGA platform and has shown the validity of the proposed solution.
