Multi bit Error Detection and Correction Architecture for Motion Estimation in Viedo Coding Systmes

The Motion Estimation (ME) is used in video coding systems to calculate the best motion between the current frame and reference frames. Process Element (PE) is the key component of ME. Error presence in the SAD value calculates by PE will affect the quality of the ME. In this paper the Built In Self Test (BIST) is used to test the PE this Error Detection and Correction Architecture (EDCA) designed based on the Residue and Quotient (RQ) code. Which will detect the multiple errors and recover the data with reduced delay from 16 clock cycles to 8 clock cycles.
