Abstract: Motion estimation plays a vital role in today’s media applications. Hence testing of such a module is a significant concern. Even though several algorithms have been proposed in the past testing of motion estimators are seldom addressed. The proposed system describes an Error Detection and Correction (EDCA) design that detects and recovers data in the motion estimator. The system uses the Sum of the Absolute Difference (SAD) method to compute the difference in the current and reference frames. The architecture comprises of an Error Detection Circuit (EDC) and a Data Recovery Circuit (DRC) to recover the original data. A Residue-Quotient code is used to compute the change in value between the error and expected values. Built-in Self test Technique (BIST) is included in the MECA and in each of Processing Element in MECA. Thus by introducing the BIST Concept the testing can be done internally without connecting outside testing requirements. So the area (number of gates) required and time is also reduces.
