This paper develops a built-in self-detection/correction (BISDC) architecture for motion estimation computing arrays (MECAs). Based on the error detection/correction concepts of biresidue codes, any single error in each processing element in an MECA can be effectively detected and corrected online using the proposed BISD and built-in self-correction circuits. Performance analysis and evaluation demonstrate that the proposed BISDC architecture performs well in error detection and correction with minor area overhead and timing penalty.
