STORE-TO-LOAD FORWARDING BUFFER USING INDEXED LOOKUP

摘要

A microprocessor (100) may include a dispatch unit (104) configured to dispatch load and store operations and a load store unit (126) configured to store information associated with load and store operations dispatched by the dispatch unit (104). The load store unit (126) includes a STLF (Store-to-Load Forwarding) buffer (305) that includes a plurality of entries (320). The load store unit (126) is configured to generate an index dependent on at least a portion of an address of a load operation, to use the index to select one of the plurality of entries (320), and to forward data included in the one of the plurality of entries (320) as a result of the load operation.
