摘要： Extended message signaled interrupts (MSI) data are disclosed. In one aspect, MSI bits are modified to include a system level identifier. In an exemplary aspect, an upper sixteen bits of the MSI message data are modified to be the system level identifier. By providing the system level identifier within the MSI message data, an interrupt controller can verify the interrupt source.

摘要： 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.

摘要： 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.

摘要： Techniques for selecting a radio interface for an application are described. A terminal identifies locally-addressable and globally-addressable wireless networks among wireless networks available to the terminal. Radio interfaces supported by the terminal may be prioritized based on the locally-addressable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be considered in prioritizing the radio interfaces. A suitable radio interface may be selected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is preferred and any WLAN is acceptable to the application or (b) a globally-addressable WLAN is available. A WWAN interface may be selected for the application if a globally-addressable WLAN is not available.

摘要： 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.

摘要： Communicating transaction-specific attributes in a peripheral component interconnect express (PCIe) system is disclosed. A PCIe system includes a host system and at least one PCIe endpoint. The PCIe endpoint is configured to determine one or more transaction-specific attributes that can improve efficiency and performance of a predefined host transaction. In this regard, in one aspect, the PCIe endpoint encodes the transaction-specific attributes in a transaction layer packet (TLP) prefix of at least one PCIe TLP and provides the PCIe TLP to the host system. In another aspect, a PCIe root complex (RC) in the host system is configured to detect and extract the transaction-specific attributes from the TLP prefix of the PCIe TLP received from the PCIe endpoint. By communicating the transaction-specific attributes in the TLP prefix of the PCIe TLP, it is possible to improve efficiency and performance of the PCIe system without violating the existing PCIe standard.

摘要： Efficient techniques using a multi-port shared non-volatile memory are described that reduce latency in memory accesses from dedicated function specific processors, such as a modem control processor. The modem processor preempts a host processor that is accessing data from a multi-port shared non-volatile memory flash device allowing the modem processor to quickly access data in the flash device. The preemption process uses a doorbell interrupt initiated by a processor that seeks access and interrupts the processor being preempted. After preemption, the host processor may resume or restart the data access. Access control by the processors utilizes a hardware semaphore atomic control mechanism. Power control of the shared non-volatile memory modules includes at least one inactivity timer to indicate when a supply voltage to the shared non-volatile memory modules can be safely reduced or turned off. Power may be restarted by any of the processors sharing the memory, allowing fast access to the data.
