ABSTRACT:
A high performance channel-to-channel adapter for interconnecting two or more digital computers or digital data processors. Multiple input/output device addresses are recognized by the channel-to-channel adapter. The channel-to-channel adapter makes the proper processor-to-processor connection by matching device addresses. In particular, it interconnects for data transfer purposes the two processors for which the same device address has been received. The assignment of device addresses for processor use and the direction of data transfer are by conventions agreed to among the software systems executing on the interconnected processors. The channel-to-channel adapter does not have a view of these conventions. In the more general case, two device addresses are assigned by software convention to each processor-to-processor link, one address being used to transfer data in one direction and the other address being used to transfer data in the opposite direction.
