ABSTRACT:
An arbitration techique for a split transaction bus of a computer system obtains higher data throughput as a result of giving responders (e.g. memories) absolute priority over initiators (e.g. processors and I/O adapters), as a result of assigning all responders a higher priority than any initiator. Precedence is also given to retrying initiators which failed to complete a transaction because the module to which the transfer was addressed was busy. The requests from non-retrying initiators are temporarily rescinded to give precedence to the requests from retrying initiators. There is an absolute limit or bound to the number of requests which a retrying module may make before it is granted mastership of the bus to accomplish its transfer. To accomplish test and set and memory scrub transactions with a minimum time loss, the bus of the computer system creates a null conductivity cycle immediately following the cycle in which the address of the memory location to be tested and set or scrubbed is transferred.
