ABSTRACT:
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.
