This paper presents a method to protect iterative solvers from Detected and Uncorrected Errors (DUE) relying on error detection techniques already available in commodity hardware. Detection operates at the memory page level, which enables the use of simple algorithmic redundancies to correct errors. Such redundancies would be inapplicable under coarse grain error detection, but become very powerful...
Modular addition is a widely used operation in Residue Number System applications. Specific sets of moduli allow fast RNS operations such as binary conversions and multiplications. Most of them use modulo 2n − 1 and 2n ; 1 additions. This paper presents four fast and small architectures for these specific moduli targeting modern FPGAs with fast carry chains. The use of this arithmetic dedicated feature...
