摘要
Abstract
An efficient low complexity H.264 VBSME (variable-block-size motion estimation) VLSI (very large scale integrated) architecture is designed, in which a MB-size input buffer, 17×16 snake scan register array, 8×8 PE array,4×4 SAD-adder-tree are used and a four-step VBS MV generator structure is proposed to reduce the hardware cost for wireless video communication applications. Compared with the MB-level VBSME structure, the total count of gates is reduced to 37%, the delay of critical path is shorten from 9.8 ns to 8.2 ns, and nearly 50.3% power is saved and the main data-path width is narrowed to 25%, but all MB characters are reserved. Its low-hardware-complexity performance makes it suitable for the integration of H.264 encoder in wireless video communication applications.关键词
