Testing architecture for motion estimation in video coding systems
R. Rukmani, Sri Ramakrishna, M. Jagadeeswari · 2013
Motion Estimation (ME) is the critical part of any video coding system. The video quality will be affected if an error has occurred in the ME. Motion Estimation is the process of determining the motion vectors that describe the transformation from one 2D image to other, usually from adjacent frames in a video sequence. In order to test Motion Estimation in a video coding system Error Detection and Correction Architecture (EDCA) is designed based on the Residue-and-Quotient (RQ) code. Multiple bit errors in the processing element (PE) i.e., key component of a ME, can be detected and the original data can be recovered effectively by using EDCA design. Experimental results indicate that the proposed design can detect multiple bit errors and effectively recover the data with reduced area and power. The area of the proposed architecture is reduced from 1152 to 114 and the power is reduced from 143.28mW to 59.39mW.
