Abstract
A system and method of broadcasting data to multiple targets across a system bus, such as the peripheral component interconnect (PCI) bus, that does not normally support broadcast transfers, in which one target responds to the bus transaction and the remaining targets listen in on the bus transaction to receive data from the system bus. The responding target stalls the bus transaction when any of the listening targets communicate to the responding target that they are temporarily unable to accept the data on the bus.
