| 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.

| Abstract: | 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 implementatio... |
