Cost-Effective Error Detection through Mersenne Modulo Shadow Datapaths

With technology scaling leading to reliability problems and a proliferation of hardware accelerators, there is a need for cost-effective techniques to detect errors in complex datapaths. Modulo (residue) arithmetic is useful for creating a shadow datapath to check the computation of an arithmetic datapath and involves three key steps: 1) reduction of the inputs to modulo shadow values; 2) computat...
