Abstract

Motion estimation algorithms are used in various video coding systems. While focusing on the testing of ME in a video coding system, this work presents an error detection and data recovery (EDDR) design, based on the residue-andquotient (RQ) code, to embed into ME for video coding testing applications. 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. Therefore, paper describes a novel testing scheme of motion estimation. The key part of this scheme is to offer high reliability for motion estimation architecture. The experimental result shows the design achieve 100% fault coverage. And, the main advantages of this scheme are minimal performance degradation, small cost of hardware overhead and the benefit of at speed testing.
