ABSTRACT:
The present invention provides a method and apparatus for splitting a bus target response between two devices in a computer system. In one embodiment, the computer system includes a bus having a first signal line and a second signal line, a third signal line, and two agents coupled to the bus and the third signal line. The first agent claims to be a target of a transaction on the bus without decoding the address associated with the transaction by asserting the first signal on the first signal line. The second agent responds to the transaction as the target. The second agent thereafter asserts a third signal on the third signal line to coordinate deassertion of the first signal on the first signal line by the first agent and concurrent assertion of the second signal on the second signal line by the second agent.
