Abstract: BIST schemes generally focus on memory circuit; testing-related issues of video coding have seldom been Addressed this work presents an Error Detection and Data Recovery (EDDR) design, based on the Residue-and Quotient (RQ) code, to embed into ME for video coding testing applications. Additionally, the reliability issue of numerous Processing Elements (PE) in a ME can be improved by enhancing the capabilities of Concurrent Error Detection (CED). Given the critical role of Motion Estimation (ME) in a video coder, testing such a module is of priority concern. While focusing on the testing of ME in a video coding system, BIST schemes generally focus on memory circuit, testing- related issues of video coding have seldom been addressed. Thus, exploring the feasibility of an embedded testing approach to detect errors and recover data of a Motion Estimation (ME) is of worthwhile interest. An error in Processing Elements (PEs), i.e. key components of a ME, can be detected and recovered effectively by using the proposed EDDR design. Experimental results indicate that the proposed EDDR design for ME testing can detect errors and recover data with an acceptable area overhead and timing penalty. Importantly, the proposed EDDR design performs satisfactorily in terms of throughput and reliability for ME testing applications.
