摘要:
A method for controlling data transfer in a serial-ATA system includes using serial-ATA Native Command Queuing (NCQ) to issue a queue of NCQ commands to at least two serial-ATA devices. The commands include a first plurality of commands for a first one of the devices and a second plurality of commands for a second one of the devices. Each of the commands includes a respective port address of one of the at least two devices and a first command identifier identifying a command for the one of the at least two devices. The method further includes receiving a first acknowledgement, which has a port address of a first target device and a second command identifier identifying a first outstanding command for the first target device. Each of the queues of commands is sent to the at least two serial-ATA devices prior to receiving the first acknowledgement.
