EFFICIENT USAGE OF A REGISTER FILE MAPPER MAPPING STRUCTURE

摘要

A processor with a register file mapper can use a hasher to improve the distribution of mappings within a mapping structure. The hasher generates a value based, at least in part, on a thread identifier and logical register identifier. The hash value is used as an index value into the mapping structure. The hashing algorithm is chosen to provide a more even distribution of mappings within the mapping structure, reducing the amount of data written from a first level register file to a second level register file.
