Abstract
A architecture for a multifunction peripheral to service a plurality of clients simultaneously. A shared memory receives data from the plurality of clients. A channel multiplexer selects data to be routed to a peripheral, a SCSI emulator is used to logically select the peripheral. The data is then forwarded from the multiplexer via the SCSI emulator to a PCI bus, the PCI bus being physically connected with the peripheral's engine. When data needs to be sent from a peripheral to a client, it is forwarded from the PCI bridge to the SCSI emulator and routed via a demultiplexer to the shared memory wherein it is retrieved by the appropriate client. The multifunction peripheral can be interrupted while performing a first task using a first peripheral, switch to a second task needing a second peripheral, and return to the first task when completed.
