Fault tolerance in electronic systems is essential in harsh environments such as
space. However, FPGAs that can be used to accelerate various computations are
prone to configuration memory failures that determine their function. Repairing
these failures is essential to increase system resilience. For this purpose, the
partial dynamic reconfiguration controller is necessary. To design
a comprehensive system inside one FPGA, we force the controller to be on the same
FPGA with a payload circuit. We create and thoroughly test a new reconfiguration
controller to increase the system's resiliency with the ability to repair itself
during its own operation. For this purpose, the FPGA controller is in
coarse-grained triple modular redundancy to be able to recover despite the
failure of any of its modules. The proposed controller has been tested to
increase the resilience of circuits from a set of benchmark circuits. The entire
system with the controller was evaluated on an actual FPGA, where faults were
injected directly into the configuration memory of this FPGA. Reliability
parameters are measured by a platform designed for this purpose, partly directly
on the tested FPGA. As we can see from the results, the mean time to failure has
been increased by up to 69% compared to a system equipped with only triple
modular redundancy with a reasonable amount of hardware resources. The
competitive solution brings only a 42% improvement in resilience with the same
parameters.
