Abstract: A window-based constraint on issue order can be applied where a shared resource (e.g., a transfer buffer for load data) is allocated out-of-order by a first unit in a processor (e.g., a load/store unit) and freed in-order by a second unit in the processor (e.g., a unit that moves data out of the transfer buffer). The first unit can have a first issue queue and issue logic that imposes a constraint that an instruction that allocates the shared resource is only ready to issue if it is within or younger than a clearance window defined within the first issue queue, where the clearance window is defined to allow at least some out-of-order issue of instructions that allocate the shared resource.
