Abstract
Storage access blocking instructions, such as the EIEIO instruction implemented within the PowerPC architecture, block other storage access instructions at the bus interface stage as opposed to the execute stage. Therefore, cacheable instructions, and other similar instructions, are allowed to complete without being blocked by such an EIEIO instruction not ordered by the EIEIO instruction.
