A new error-tolerant finite impulse response (FIR) filter architecture for low-power high-performance applications is presented. The combination of low-cost residue coding and a novel structure, called modulo bitplane, proves to be very efficient. Results for single-error correction of a typical 12-tap programmable FIR filter with 6-bit sample data and 8-bit coefficients show that area exhibits just 85% overhead.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
