    摘要: A method for adaptive Bluetooth low power wake up and discovery is provided whereby wake-up triggers are uploaded to Media Access Control (MAC) firmware. A data stream representing a trigger arrives as either an interpretable binary stream of instructions, or as a concatenation of events listed in a preset table. Various parameters allowing flexible wake-up triggering, such as Service Set Identifiers (SSIDs) to scan for probability likelihoods, are also uploaded. Both table-based and interpretable instructions are designed to ensure the security of the trigger by limiting the functionality of the trigger to only trigger-related events (e.g., scanning, pre-reserved memory). Both the table and the instruction set are designed in a minimalistic fashion to allow a slim and fast firmware-side implementation. Insignificant modifications to existing computer or Operating System (OS) architecture take advantage of the already existing MAC processor in many 802.11 interfaces, offering enormous flexibility.

    摘要: Processes to achieve low power discovery and wake-up in the presence of desired 802.11 coverage are disclosed. In one aspect, probabilistic scanning for 802.11 SSID triggers is provided. In another aspect, the 802.11 Access Point (AP) is equipped with a Bluetooth inquiring device, which initiates the wake-up process with a special inquiry access code (IAC). The special IAC can comprise the AP's 802.11 channel. Additional optional sensors (GPS, Gyroscope, odometer, etc) are provided such that probabilistic scanning reduces power consumption and improves the likelihood that an 802.11 channel scan will find a desired SSID. A Bluetooth inquiry allows a discovery process to either wake-up immediately, or ascertain the need for host wake-up by exchanging further information with the AP. Probabilistic scanning allows the use of sensors and historical or pre-loaded information to improve the probability that 802.11 scanning is not required on individual channels, further driving down power needs.

    摘要: Methods and devices for testing a physical layer (PHY) of an asymmetrical interconnect interface using a traffic generator/analyzer (TGA) are described. At least one special PHY test sequence is transmitted to the asymmetrical interconnect interface during link start up to place the device under test in PHY testing mode in which the TGA is used to generate and analyze data. The asymmetrical interconnect interface can then receive a configuration command and configure the asymmetrical interconnect interface in response to the configuration command. The asymmetrical interconnect interface can then use the TGA to transmit test sequences to, or receive test sequences from, e.g., a tester, on at least one identified lane of the asymmetrical interconnect device, which at least one identified lane is set by the configuration command.

    摘要: A method of communicating between a transmitter and a receiver based on frames is provided. An error detection code is added to each frame to be transmitted by the transmitter. The frames to be transmitted by the transmitter are transmitted and the transmitted frames are received by the receiver. An error detection code is re-computed based on the received frames by the receiver. At least one frame which has been correctly received based on a comparison of the error detection code of each frame with the re-computed error detection code of each received frame is acknowledged. An error indication frame is sent by the receiver when an error is detected based on the comparison result. If a retransmission condition is detected by the transmitter by receiving an error indication frame from the receiver or if no acknowledgement frame was received by the transmitter from the receiver in a predetermined time interval, the currently transmitted frame is aborted and the transmitter inserts a trailer. As a further possibility instead of inserting a trailer, the start of re-transmission can be indicated by using a retransmission indicator.

    摘要: A data processor system is described comprising a first and a second data processor unit (PU1, PU2). The first data processor unit (PU1) has a data source (SW1, IP11, IP 12) for providing data units for transmission to the second data processor unit (PU2) and a retry buffer (RBUF) for temporarily storing transmitted data units. It is provided with a data selector (RSEL) for selecting data units from the data source or from the retry buffer, and a controller (RCTRL) for controlling the data selector, as well as an output (T1x) for providing data selected for transmissions. The second data processor unit (PU2) has an input (R1x) for receiving the transmitted data and an output (PU20) for further transmitting the received data to a third data processor unit. It also has an input buffer (IBUF) coupled to the input, for temporarily storing the received data. The second data processing unit further comprises an error detector (ED) for detecting an error in the received data and a message generating unit (EF) coupled to the error detector for generating an error message for the first data processor unit in case the error detector detects an error. The controller (RCTRL) of the first data processor unit causes the data selector to select data from the retry buffer (RBUF) if it receives an error message, and causes the data selector to select the data source (SW1, IP11, IP 12) otherwise. The first data processor unit (PU1) limits retransmission of a data unit to a predetermined maximum number of times irrespective of whether the data unit is correctly received or not. This allows for an undisturbed flow of streaming data with an increased reliability.
