Efficient scheduling of load instructions

Abstract:

When scheduling instructions for execution on a computing device, load instructions are processed before their dependent computational instructions. This can result in the load instructions being scheduled in a non-optimal order. To schedule the load instructions in a preferred order, a scheduler can speculatively schedule the load instructions without committing to their order. Subsequently, when the scheduler encounters the dependent computational instructions, the scheduler can reorder the speculatively scheduled load instructions according to the execution order of the dependent computational instructions.
