Abstract

Many techniques and design tools have been developed for mapping algorithms to array processors. Linear mapping is usually used for regular algorithms. Large and complex problems are not regular by nature and regularization may cause a computational overhead which prevents the ability to meet real-time deadlines. In this paper, a systematic design methodology for mapping partially-regular as well as regular Dependence Graphs is presented. In this approach the set of all optimal solutions is generated under the given constraints. Due to nature of the problem and the tight timing constraints of real-time systems the set of alternative solutions is limited. An image processing example is discussed.
实时系统阵列处理器设计的广义方法
为了将算法映射到阵列处理器,已经开发了许多技术和设计工具。线性映射通常用于正则算法。大型和复杂的问题本质上是不规则的,而正则化可能会导致计算开销,从而妨碍满足实时截止日期的能力。本文提出了一种映射部分正则关系图和正则关系图的系统设计方法。该方法在给定约束条件下生成所有最优解的集合。由于问题的性质和实时系统的严格时间约束,备选解决方案的集合是有限的。讨论了一个图像处理实例。
