Eine transparente Brücke zwischen Bussen eines Computersystems und ein Verfahren für die Schnittstellenbildung der Busse, um als ein einziger logischer Bus zu arbeiten

A bridge and a method for interfacing a plurality of buses with the bridge provides electrical isolation between the buses but is transparent so that the plurality of buses is viewed by software as a single logical bridge. Transaction cycles initiated on one bus are reflected on the other bus. A speculative start of a transaction cycle on a secondary bus immediately after the transaction cycle has been started on the first bus provides a significant savings in time to complete transactions in which the target of the transaction is on the secondary bus.
