摘要： A method and system for communicating data between two devices are described herein. The method detects an electrical signal of a first protocol from a first device in a repeater, wherein the first protocol comprises single-ended signaling. The method also determines the speed of the electrical signal. Additionally, the method converts the electrical signal of the first protocol into an electrical signal of a second protocol based on the speed of the electrical signal. The second protocol comprises differential signaling. Furthermore, the method sends the electrical signal of the second protocol to a second device. In addition, the method stops the electrical signal of the second protocol to the second device when the electrical signal of the second protocol indicates an end of data flow.

摘要： Techniques and mechanisms for exchanging debug information with a repeater and multiplex logic of a platform. In an embodiment, the multiplex logic can be configured to any of multiple modes including a first mode to exchange debug information between the repeater and debug client logic of the platform. Another of the multiple modes may provide an alternate communication path for exchanging functional data, other than any debug information, between the repeater and a physical layer interface of the platform. In another embodiment, the repeater is compatible with a repeater architecture identified by a universal serial bus standard. The physical layer interface is compatible with an interface specification identified by the same universal bus standard.

摘要： Systems and methods of operating a serial interconnect interface provide for generating a pulse in response to a state change in a data signal of the serial interface interconnect, and transmitting the pulse from a physical layer of the serial interconnect interface to a link layer of the serial interconnect interface. The duration of the pulse can be selected based on whether the state change corresponds to an end of packet (EOP) condition. In addition, the data signal may include a non return to zero invert (NRZI) encoded signal, wherein the pulse is part of a digital NRZI signal.
