A Novel Robust Core for Detecting Node Failures in FPGA Clusters

Field Programmable Gate Arrays (FPGAs) are gaining popularity in different fields, including space applications, where high computational capabilities are required; for this reason, FPGAs are often used as nodes in clusters. When considering mission-critical systems, reliability must be ensured, even in radiation environments such as space. Thus, it is necessary to define a way of monitoring the entire system, ensuring the correct behavior of each node. This work introduces the Beacon Controller, a module to be implemented on the FPGA elements of a cluster for real-time monitoring of the computational elements of the node.
