摘要
介绍一种在可重构媒体处理器ReMAP上实现小数运动估计的方法。ReMAP处理器由可重构的运算单元阵列和互联单元级联组成,具有高度可重构性和强大的并行计算能力。在ReMAP中映射实现了小数运动估计中的1/2插值、1/4插值和搜索等算法。通过算法的仿真验证分析,ReMAP可支撑小数运动估计的高性能实现,达到或接近ASIC的性能,并具有较好的应用灵活性,适于媒体处理应用。
A method to implement fractional motion estimation(FME) on ReMAP was presented.Consisting of reconfigurable processing element cascaded with interconnect element,the ReMAP is highly reconfigurable and powerful in parallel computation.Half-pixel interpolation and quarter-pixel estimation of fractional motion estimation were mapped on ReMAP,respectively.Mapping of the algorithm was simulated and verified,and the result was analyzed.It has been shown that,with the proposed method,high performance implementation equal to or near ASIC could be achieved on ReMAP.The proposed implementation method is adaptable to various applications,especially to media processing.
