Abstract—We present an architectural framework for Nmodular
redundant system exploiting the dynamic partial reconfiguration
capability of FPGA. Only one instance of a Functional
Element (FE) is retained on the datapath and the other instances
undergo test subjected to the actual inputs of a system. A
software based voter periodically monitors the health of the FE’s
replications thereby avoiding a hardware voter in the datapath
of an active FE. The defective behavior of an active FE triggers
the reconfiguration process and a healthy element is introduced
into the datapath. Furthermore, the configuration bitstreams are
protected in the flash memory using Reed-Solomon codes owing
to their multi-bit error correcting capability. Together, dynamic
plus static hybrid fault-handling methodology is shown to provide
promising fault coverage at very low latency overhead.
