Abstract :
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 it exhibits just 85% area overhead.
