Abstract
Transactions are scheduled over a half duplex link between a first device and a second device. Information flowing over the half duplex link is divided into a plurality of service periods. According to one embodiment of the present invention, the transfer of a read request transaction, from the first device to the second device, is scheduled in one service period. The transfer of a write transaction, from the first device to the second device, is scheduled such that the write transaction will not be transferred across the half duplex link in the same service period as returning memory read data is transferred across the half duplex link. According to another embodiment of the present invention, a first transaction associated with a first agent is scheduled in a first service period according to a global schedule. The global schedule associates the first service period with the first agent. A second transaction associated with a second agent is scheduled in a second service period according to the global schedule. The global schedule associates the second service period with the second agent.
