Enforce In-Order Execution of I/O is an assembly language instruction used on the PowerPC computer processor used to prevent one memory or I/O operation from starting until the previous memory or I/O operation completed. This instruction is needed as I/O controllers on the system bus require that accesses follow a particular order, while the CPU reorders accesses to optimize memory bandwidth usage. [1]
