摘要
According to one aspect of the invention, a method is provided in which store addresses of store instructions dispatched during a last predetermined number of cycles are maintained in a first data structure of a first processor. It is determined whether a load address of a first load instruction matches one of the store addresses in the first data structure. The first load instruction is replayed if the load address of the first load instruction matches one of the store addresses in the first data structure.
