METHOD AND APPARATUS FOR ADDRESS DISAMBIGUATION

摘要

A scheduling unit is described for scheduling an execution order of a first instruction of a first type (503) and a second instruction of a second type (506) in an instruction stream where the second instruction precedes the first instruction. The scheduling unit comprises a table that records address component identifiers corresponding to the second instructions (503). An address comparator is coupled to the table. The address comparator compares address component identifiers that corresponds to the first instruction with address component identifiers on the table (504). The scheduling unit schedules the first instruction to be executed ahead of the second instruction when the address component identifiers differ from the address component identifiers on the table (506).
