摘要:
The present invention relates to a secondary channel for a point-to-point burst style bus associated with a computer system. The point-to-point bus may originate as a standardized bus from a fibre channel controller. The point-to-point bus connects to another circuit which may be a bridge circuit, a minicomputer or a peripheral device. A secondary channel is also connected to the point-to-point bus and is adapted to share the bus by receiving information having predetermined addresses. The information recieved by the secondary channel can be stored in a memory that is shared with a processor. Command/control information can be extracted from the point-to-point bus before data is transferred through the bridge circuit in order to allow the data to be acted on more quickly by processing/storage devices since the control data was already made available to the storage devices via the secondary channel.
摘要:
A system for transferring data includes structure (i.e, hardware, software, a combination thereof) for requesting data from a second bus, which data is destined for a first bus; and structure for gaining ownership of the second bus for the purpose of transferring the data from the second bus to the first bus, which structure includes substructure for waiting a programmably variable amount of time to see if additional data is requested by the first bus, before relinquishing control of the second bus.
