New architectures for systolic hashing

Abstract

Two- and three-dimensional systolic architectures are proposed for the hash table data structure (hashing). The parallel systolic hashing architecture provides the facility for implementing the hash operations of Insert, Delete, and Member in a constant time complexity. The importance and advantages of extending sequential hashing to a parallelized form are discussed. An implementation is presented of a sorting problem of N numbers in an O(L) time complexity, where L is constant, using a three-dimensional parallelized systolic hashing process. This is compared to a sequential hashing process, which requires O(N) time complexity.<>
