PROCESSING SYNONYMS OF EFFECTIVE ADDRESSES IN A LOAD-STORAGE UNIT THAT WORKS WITHOUT ADDRESSING

摘要

Technical solutions for issuing a plurality of instructions from an out-of-order (OoO) window by a load-storage unit (LSU) are described. In response to determining that a first effective address is used by a first instruction, where the first effective address corresponds to a first real address, outputting includes creating an effective real table (ERT) entry in an ERT, wherein the ERT entry assigns the first effective address to the first real address. In addition, in response to determining an effective address synonym that is used by a second instruction, the execution includes the effective address synonym being a second effective address that also corresponds to the first real address: creating an entry of a synonym identification table (SDT) in an SDT, the SDT entry assigning the second effective address to the ERT entry, and restarting the second instruction by replacing the second effective address in the second instruction with the first effective address.
