  • Patent number: 10019385
    Abstract: Described is an apparatus comprising a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be an elastic buffer coupled to a received clock, a local clock, a received-clock data, and a local-clock data. The second circuitry may assert a first flag when a set of values on the received-clock data matches part of a skip ordered set. The third circuitry may assert a second flag when a set of values on the local-clock data matches part of the skip ordered set. The fourth circuitry may increment a count value upon assertion of the first flag and may stop incrementing the count value upon assertion of the second flag. In some embodiments, additional circuitries may extract a first timestamp from a packet, sum the first timestamp and the count value, and substitute the sum for the first timestamp within the packet.

  • Patent number: 9959222
    Abstract: A first state of an interconnect protocol is entered. A particular signal is sent according to the protocol to a device over a link. During the first state, it is detected that a response to the particular signal is received in the first state. It is determined that the device supports a configuration mode outside the protocol based on the received response. The configuration mode is entered based on the response. One or more in-band configuration messages are sent within the configuration mode.

  • Publication number: 20170262403
    Abstract: A system and method is described for simplifying implementation of repeater (e.g., re-driver/re-timer) module implementation in high-data-rate interconnects that carry a relatively low-data-rate clock signal as well as the data stream (e.g., PCIe). At the endpoint, any information critical to the function of the repeater (e.g., the most recent data rate negotiated by a pair of endpoints communicating through the repeater) is embedded in the clock signal by pulse-width modulation as ordered sets. The repeater only needs to read the clock-embedded information rather than decoding the data stream. Thus repeaters for such applications reconstruct the high-rate data-stream while actually decoding only the low-rate clock signal. Because the clock-signal protocol is independent of the data-stream protocol, the repeater's operation is protocol-agnostic with respect to the data-stream.

  • Patent number: 9525539
    Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels. In some embodiments, a contention-based channel access procedure may be performed to attempt to gain access to both a primary channel and an auxiliary channel. A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted.

  • Patent number: 9355057
    Abstract: 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.
