1. An out of order processor, comprising: a virtual load store queue for allocating a plurality of loads and a plurality of stores, wherein more loads and more stores can be accommodated beyond an actual physical size of a physical load store queue of the processor; wherein the processor allocates other instructions besides loads and stores beyond the actual physical size of the physical load store queue; and wherein the other instructions can be dispatched and executed even though intervening loads or stores do not have spaces in the physical load store queue, wherein as loads retire out of the virtual load store queue, a load dispatch window moves to subsequent instructions in a sequence and will include more allocated loads to be considered for dispatch equivalent to a number of loads that have retired from the virtual load store queue.
