摘要

奇偶合并是一种广泛使用且被普遍接受的合并网络，它使用O(N log/sup 2/N)比较器和O(log/sup 2/N)延迟。提出了一种新的合并网络，推广了奇偶合并技术。它基于输入键除以指定的模数，不限于2。在最后的合并步骤中使用一个特殊的比较器，它接受m个输入行并产生m个排序项，其中m是为合并选择的模数。讨论了适用于双onic合并网络的备选方案。

A modulo merge sorting network

The odd-even merge is a widely used and generally accepted merging network that uses O(N log/sup 2/N) comparators with O(log/sup 2/N) delay. A novel merging network is presented that generalizes the technique used in the odd-even merge. It is based on the division of the input keys by a specified modulus, not limited to 2. A special comparator is used in the final merge step that accepts m input lines and produces m sorted items, where m is the modulus selected for the merge. Alternatives are discussed that apply to the bitonic merging network.<>
