A dependable and dynamic network on chip suitable for FPGA-based reconfigurable systems

Abstract

In this paper, we present a new reliable and dynamic NoC-based communication approach called RCuNoC designed for the FPGA-based reconfigurable systems. The originality of the RCu routers are the online capacity to detect data packet errors and localize if the errors come from input ports or inside of the routers while distinguish between temporary and permanently errors. Our reliable router which requires a low-area architecture is based on the centralization of the buffer, routing logic and error detection/correction/localization blocks. We present the basic concept of the RCu switches, its main advantages and with regards to the other main already proposed dynamic NoC approaches and we prove its feasibility on examples through the simulations. Performance evaluation and FPGA implementation results are also given.
