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