摘要：A novel memory hashing system is disclosed. The system converts an addressinto a hashed address of the form (B,C) where B is a module number in a multi-modulememory system and C is an offset in the module. The system can be shown to have nopathological cases for any stride value less than some predetermined value. An

apparatus according to the present invention is conveniently implemented in a pipelinedarchitecture which allows one address value to be calculated each memory cycle. Thepresent invention utilizes a special matrix calculated from a primitive polynomial forcalculating the hashed addresses. The conversion of any given address requires one rowof the matrix. The entries of the matrix may be stored in ROM. Alternatively, the requiredrow of the matrix may be calculated in response to receiving the address which is to beconvened to the hashed address.
