Summary: | Processor-based digital systems are increasingly being used in safety-critical environments. To meet the associated safety requirements, these systems are usually characterized by a certain degree of redundancy. This paper proposes a concept to introduce a redundant processor on demand by using the partial reconfiguration capability of modern FPGAs. We describe a possible implementation of this concept and evaluate it experimentally. The evaluation focuses on the fault handling latency and the resource utilization of the design. It shows that an implementation with 32 KiB of local processor memory handles faults within 0.82 ms and, when no fault is present, consumes less than 46% of the resources that a comparable static design occupies. |
