Online self-repair of FIR filters

Chip-level failure detection has been a target of research for some time, but todayʹs very deepsubmicron technology is forcing such research to move beyond detection. Repair, especially self-repair, has become very important for containing the susceptibility of todayʹs chips. This article introduces a self-repair-solution for the digital FIR filter, one of the key blocks used in DSPs.
