Modern networks-on-chip (NoC) for embedded systems are manufactured by thin design rules; they should be resistant to failures due to the specific aspects of the technology. In the paper we consider failure mitigation approaches, evaluate them for thin design rules. Most fault mitigation approaches are based on reconfiguration of NoC and its main components – routers. We suggest the methodology for development of reconfigurable routers with fault mitigation, estimate them using simulation that enables dynamic failure injection. The proposed method can be used for routers with different structures in NoC with various interconnection graphs.
The SpaceFibre standard has appeared relatively recently. Also SpaceFibre standard supports several "Quality of Service" mechanisms. It includes best effort, bandwidth reserved, scheduled and priority based qualities of service. It is implemented by means of virtual channels. Standard does not fully describe network layer in the latest version (ECSS Draft F3). The rules for transferring data at the network layer also affect the quality of service.In this paper we present analysis and an implementation of the SpaceFibre network layer. The switch matrix's channels quantity connected to port (connection point) is one. Low priority packet transmission can be interrupted, if a packet with a higher priority is received. Interruption rules will be described, data transmission latency characteristics and performance will be evaluated. Analysis and modeling of the proposed network level implementation will be demonstrated. Data packets of different sizes were used during simulation. Number of virtual channels is 4 for the research.Index Terms-SpaceFibre, Quality of service (QoS), Network level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
