Abstract
A processor that executes instructions out of program order is described. In some implementations, a processor detects whether a second memory operation is dependent on a first memory operation prior to memory address calculation. If the processor detects that the second memory operation is not dependent on the first memory operation, the processor is configured to allow the second memory operation to be scheduled. If the processor detects that the second memory operation is dependent on the first memory operation, the processor is configured to prevent the second memory operation from being scheduled until the first memory operation has been scheduled to reduce the likelihood of having to reexecute the second memory operation.
