A Novel Architecture for Inter-FPGA Traffic Collision Management

Abstract : —with the increasing complexity of various communi-cations and applications, Network-On-Chip (NoC) is one of the most efficient communication structures. Multi-FPGA platforms are considered as the most appropriate experimental solutions to emulate a large size of MPSoCs (Multi-Processor System-on-Chip) based on a NoC. The deployment of the NoC into several FPGAs requires the use of inter-FPGA communication links. The number and performance of external links restrict the bandwidth of communication. Currently, the number of inter-FPGA signals is considered as a substantial problem in NoC implemented on Multi-FPGA architectures. In this paper, we propose the integration of the collision management architecture connected to the NoC. Two collision avoidance algorithms are proposed in the structure to balance the load injected between all routers connected with one external link. This architecture leads to high timing performances in multi-FPGA system communications. The results demonstrate the efficiency of the collision management structure connected to the NoC. The collision management algorithm is chosen according to the type of inter-FPGA communication requirements.
