ABSTRACT

  A significant amount of research has been done towards finding a technique that will allow maximum use of parallel capabilities in the case of nested loops. The last couple of years have seen a number of theoretical results that attempt to gain the largest possible amount of parallelism. In this paper, one such technique - multidimensional retiming - is integrated with a novel implementation of the way the indices are used to control the loop iterations to provide a practical approach to the parallelization problem. Previous approaches have considered the problem as a whole and emphasized the use of multiple processors, without optimizing the execution for an individual processor. This paper looks at an efficient implementation of nested loops for a single processor. The theory and the algorithm used to achieve the desired result are presented. A detailed example illustrates the use of the technique.
