A Resource-Saving Approach for Adding Redundancy to a Network-on-Chip System

摘要

FPGAs (Field programmable Gate Arrays) are useful compo-nents for embedded systems. In combination with Systems-on-Chip and Networks-on-Chip they enable flexible system solutions. Reliability and fault tolerance in such systems often is implemented by adding components for redundancy. Due to constraints in structural resources of FPGA chips, this approach in many cases does not provide adequate solutions. Indirect re-dundancy combined with universal component monitoring is a solution for failsafe Systems-on-Chip / Networks-on-Chip appli-cations in such situations.
