简介：与exascale来超级计算的时代，电源效率成为了最重要的障碍造一个exascale系统。Dataflow建筑学在为科学应用完成高电源效率有本国的优点。然而，最先进的dataflow体系结构没能为循环处理利用高并行。处理这个问题，我们建议一个pipelining环优化方法(PLO)，它在处理元素(PE)在环流动做重复dataflow的数组加速器。这个方法由二种技术，帮助建筑学的硬件重复和帮助说明的软件重复组成。在硬件重复执行模型，一个在薄片上循环控制器被设计产生循环索引，减少计算内核并且打为pipelining执行的一个好基础的复杂性。在软件重复实行模型，另外的环指令被论述解决重复相关性问题。经由这二种技术，准备好了每周期执行的指令的平均数字被增加使浮点联合起来忙。当这二种技术的硬件费用是可接受的时，模拟结果证明分别地，我们的建议方法平均由2.45x和1.1x在浮点效率超过静电干扰和动态循环执行模型。

简介：主成分分析(PCA)和线性判别分析(LDA)是统计模式识别地里的二种流行特征抽取技术。不能直接由于小样品尺寸问题LDA被用于基于外观的面貌识别任务。作为后果，很多基于LDA的面部特征抽取技术被建议相继地处理这个问题。Nullspace方法是在他们之中的最有效的方法之一。Nullspace方法试着发现在在内班scatter矩阵的零空间最大化在班之间scatter的一套判别式向量。它的判别式向量的计算将涉及在一个高度维的矩阵上执行奇异值分解。它通常消费记忆、费时间。在统计分析在Nullspace方法和变化的系数的概念借关键想法我们在场新奇面部特征抽取法，即，判别式基于在这篇论文的变化(DCV)的系数。在FERET和AR脸图象数据库上执行的试验性的结果证明DCV是与Eigenfaces，Nullspace方法，和另外的最先进的美容比较的一种有希望的技术特征抽取法。电子增补材料这篇文章(doi:10.1007/s11390-007-9070-2)的联机版本contatins增补材料，它对授权用户可得到。
