Networks on chip (NoCs) present viable interconnection architectures which are especially characterized by high level of parallelism, high performances and scalability. The already proposed NoC architectures in literature are mostly destined to system-on-chip (SoCs) designs. For a FPGA-based reconfigurable system, the proposed NoCs are not suitable. In this paper, we present a new high-performance interconnection approach destined for FPGA-based reconfigurable system. Our proposed NoC is based on a scalable communication unit characterized by its particularly architecture, an arbitration policy based on the priority-to-the-right rule and high performances. We present the basic concept of this communication approach and we prove its feasibility on examples through the simulations. Implementation results are also detailed.
