Previous work has focused on implementing pixel truncation using a fixed-blocksize (16 × 16 pixels) ME. However, pixel truncation fails to give satisfactory results for smaller block partitions. In this paper, we analyze the effect of truncating pixels for smaller block partitions and propose a method to improve the frame prediction. Our method is able to reduce the total computation and memory access compared to conventional full-search method without significantly degrading picture quality. With unique data arrangement, the proposed architectures are able to save up to 53% energy compared to the conventional full-search architecture. This makes such architectures attractive for H.264 application in future mobile devices. 2009-12-11T08:39:22Z 2009-12-11T08:39:22Z 2009-09 Article IEEE Transactions on Circuits and Systems for Video Technology, vol.19 (9), 2009, pages 1251-1261. 1051-8215 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=4914842 http://hdl.handle.net/123456789/7407 en Institute of Electrical and Electronics Engineers (IEEE) |
