Abstract
An improved method of supporting service requests in certain bus architectures is disclosed. According to the presently invented method, the source, instead of using its own arbitration number, uses the arbitration number of the destination when performing an interrupt or DMA request. The destination then recognizes that it has been granted bus ownership, even though it was not arbitrating for the bus originally. The destination can therefore immediately assume that a request has occurred and immediately thereafter begin its request service routine.
