<p>The invention resides in a computer system (10) having a universal channel and control unit (14, 16) to interface to a plurality of different I/O adapters (18, 20) or devices (22, 24). The system comprises a main processor (21) and associated memory (23), and a channel, coupled to the processor and memory, to access the processor and memory. The channel has a first I/O protocol. A bus is connected between the processor/memory and the channel, and a control unit is connected to the channel and the bus, and interfaces the channel to a plurality of different I/O adapters or devices. Each of the I/O adapters or devices has a different protocol than the other I/O adapter or device and different than the first I/O protocol. The control unit is preferably integrated with the main processor.</p> |
