Abstract: Some interface signals are selected from among signals of a plurality of different parallel interfaces, then being multiplexed onto a serial connection. A transmitter of a signal transmission system includes an interface-signal selector IFS, and a transfer programmer TP for issuing a control signal to instruct the selection from among the parallel interfaces. The transfer programmer TP implements the multiplexing of the selected interface signals in such a manner that the specification of the parallel interfaces is satisfied. Also, the transfer programmer TP changes, as occasion requires, the control signal to instruct which interfaces to select. This change allows the interface signals to be multiplexed onto the serial connection while dynamically changing the interface signals to be multiplexed.

Abstract: One embodiment of the present invention sets forth a technique for reducing the latency associated with media protection notification for serial interface mass storage devices, such as serial AT attachment (SATA) hard disk drives. A new link layer primitive, referred to as hold-emergency (HOLDE), incorporates the flow-control behavior of the existing HOLD command, with the additional new action of notifying the hard disk drive to take emergency steps to prepare for impact. The HOLDE link layer primitive operates in conjunction with the existing hold-acknowledge (HOLDA) primitive and is semantically similar to the existing HOLD primitive. The HOLDE mechanism is preferably implemented directly in hardware in the SATA link layer state machines within the host and the hard disk drive.
