Abstract: Systems and methods for time synchronization for clocks separated by a communication link allow a master clock to be positioned at a downstream-facing port or an upstream-facing port and to send synchronization commands with an associated time stamp embedded in transport layer protocol (TLP) prefixes to a slave clock. The slave clock may update its time value based on the received time stamp. Further, the slave may calculate a round trip delay between the master clock and the slave clock and use this delay calculation to correct the slave clock. The delay calculation may likewise be made using TLP prefixes. By using TLP prefixes in this fashion, the time synchronization can piggyback on existing message traffic, which reduces signaling overhead. Likewise, by using the TLP prefixes, the time synchronization may be initiated from either an upstream-facing port or a downstream-facing port.

Abstract: Coherency driven enhancements to a PCIe transaction layer are disclosed. In an exemplary aspect, a coherency agent is added to a PCIe system to support a relaxed consistency model for use of memory therein. In particular, endpoints can request ownership of portions of the memory to read from and write to the memory. The coherency agent assigns an address range including the requested portions. The requesting endpoint copies the contents of the memory corresponding to the assigned address range into local endpoint memory to perform read and write operations locally. The owning endpoint may provide an updated snapshot of the copied memory contents upon request. At completion of use of the copied memory contents, or upon request from the coherency agent, ownership of the address range reverts back to the root complex, and the endpoint sends the updated contents back to the address range in the system memory element.

Abstract: Removable memory card discrimination systems and methods are disclosed. In particular, exemplary embodiments discriminate between secure digital (SD) cards and other removable memory cards that comply with the SD form factor, but support the Universal Flash Storage (UFS) protocol. That is, a host may have a receptacle that supports the SD card form factor and is configured to receive a device. In use, a removable memory card is inserted into the receptacle and, using an SD compliant interrogation signal, the host interrogates a common area on the card so inserted. The common area includes information related to capability descriptors of the card. An SD compliant card will respond with information such as capability descriptors about the SD protocol capabilities, while a UFS compliant card will respond with an indication that the card is UFS compliant. The host may then restart the communication with the card using the UFS protocol.

Abstract: In a device comprising a serial bus and a plurality of devices, register/address mappings and/or unique group identifiers are used to convey additional information in messages/datagrams over the serial bus without explicitly sending such information in the message/datagram. Such register/address mappings may be done beforehand, and in conjunction with group-specific identifiers, may reduce transmission latency by keeping the size of the messages/datagrams small. Since all devices on the serial bus have prior knowledge of such register/address mappings and/or group-specific identifiers, recipient devices are able to infer information from the group-specific identifiers and/or register/address sent in each message/datagram that is not explicitly sent within such message/datagram.

Abstract: Alternate acknowledgment (ACK) signals in a coalescing Transmission Control Protocol/Internet Protocol (TCP/IP) system are disclosed. In one aspect, a network interface card (NIC) examines packet payloads, and the NIC generates an ACK signal for a sending server before sending a coalesced packet to an internal processor. Further, the NIC may examine incoming packets and send an ACK signal to the internal processor for ACK signals that are received from the sending server before sending the coalesced packet to the internal processor. By extracting and sending the ACK signals before sending the corresponding payloads in the coalesced packet, latency that would otherwise be incurred waiting for the ACK signal is eliminated. Elimination of such latency may improve network performance and may provide power savings.

Abstract: Techniques for graceful coexistence of modules supporting multiple communication protocols (210, 220) are described. Graceful coexistence may be achieved by giving priority to a communication protocol having high priority data (310, 320) to send or receive. In one design, the priority of data to send via a wireless channel by a first module (210) for a first communication protocol (e.g., IEEE 802.11) may be determined, e.g., based on data type, one or more data protocol header fields, an application originating the data, etc. Whether to send the data without delay may be decided based on the priority of the data. A second module for a second communication protocol (e.g., Bluetooth) may be requested to not transmit (220) on the wireless channel in response to a decision to send- the data without delay. The data may be sent via the wireless channel upon receiving an indication that the wireless channel is not occupied by the second module.

Abstract: Techniques for performing WLAN system scanning and selection are described. A terminal performs multiple iterations of scan to detect for WLAN systems. A scan list containing at least one WLAN system to detect for is initially determined. For each scan iteration, a scan type may be selected from among the supported scan types. The selected scan type may indicate passive scan or active scan, frequency channels to scan, etc. A scan may be performed based on the selected scan type. Signal strength measurements are obtained for access points received during the scan and used to identify detected access points. After all scan iterations are completed, candidates access points are identified based on the scan results, e.g., based on the signal strength measurements for the detected access points and a detection threshold. The best candidate access point may be selected for association by the terminal.
