Abstract:
Methods and apparatus for managing an effective address table (EAT) in a multi-slice processor including receiving, from an instruction sequence unit, a next-to-complete instruction tag (ITAG); obtaining, from the EAT, a first ITAG from a tail-plus-one EAT row, wherein the EAT comprises a tail EAT row that precedes the tail-plus-one EAT row; determining, based on a comparison of the next-to-complete ITAG and the first ITAG, that the tail EAT row has completed; and retiring the tail EAT row based on the determination.
