Abstract
A method and apparatus that provides for the atomic transfer of data associated with a command to be transferred to a device consisting of a cache memory which supports a plurality of virtual devices. The atomic transfer enables the device to initiate and complete execution of the command immediately with respect to a particular virtual device without having to wait for data to come during subsequent bus transfers. This insures that the state of the device will be consistent during execution of the command.
