    • An interface system includes a secure digital (SD) driver module to communicate with an SD card over a bus, a secure digital input/output (SDIO) driver module to communicate with an SDIO card over the bus, and an input/output port. A method of operating a host in the interface system includes coupling the bus to the SD card while a first mode is enabled, coupling the bus to the SDIO card while a second mode is enabled, and enabling the first mode in response to a request for access to the SD card. The method includes, while the first mode is enabled, (i) listening for a notification signal arriving from the SDIO card via the input/output port, indicating that an interrupt is pending at the SDIO card, and (ii) in response to the notification signal, enabling the second mode to allow the SDIO card to transmit the interrupt to the host.
    • 接口系统包括一个通过总线与SD卡通信的安全数字(SD)驱动器模块,用于通过总线与SDIO卡进行通信的安全数字输入/输出(SDIO)驱动器模块以及输入/输出端口。 在接口系统中操作主机的方法包括在启用第一模式的同时将总线耦合到SD卡,而在启用第二模式时将总线耦合到SDIO卡,并且响应于对第一模式的请求 访问SD卡。 该方法包括,当第一模式被使能时,(i)监听通过输入/输出端口从SDIO卡到达的通知信号,指示中断在SDIO卡处于等待状态,以及(ii)响应于 通知信号,使第二种模式允许SDIO卡向主机发送中断。

    • Methods and systems are described for providing Bluetooth and Wi-Fi coexistence on an electronic device. Aspects of exemplary embodiments include determining Bluetooth link parameters for a Bluetooth connection and Wi-Fi link parameters for a Wi-Fi connection. Also, a Bluetooth path loss for the Bluetooth connection and a Wi-Fi path loss for the Wi-Fi connection can be determined. According to this embodiment, one or more link conditions, based upon one or more of the Bluetooth link parameters, the Wi-Fi link parameters, the Bluetooth path loss, and the Wi-Fi path loss, may be calculated to determine if simultaneous collaboration between the Bluetooth connection and Wi-Fi connection is feasible. In response to simultaneous collaboration being feasible, the Bluetooth link parameters and the Wi-Fi link parameters are customized based on the one or more link conditions to permit simultaneous collaboration between the Bluetooth connection and the Wi-Fi connection.

    • An interface system includes a first driver module that communicates through a bus with a first peripheral card when the bus is in a first mode. A second driver module communicates through the bus with a second peripheral card when the bus is in a second mode. A bus control module receives a communication notification signal from the second peripheral card when the first peripheral card is communicating with the first driver module. The communication notification signal does not interfere with the communication of the first peripheral card and the first driver module. The bus control module switches the bus between first and second modes in response to the communication notification signal.
    • 接口系统包括当总线处于第一模式时通过总线与第一外围卡进行通信的第一驱动器模块。 当总线处于第二模式时,第二驱动器模块通过总线与第二外围卡进行通信。 当第一外围卡与第一驱动器模块通信时,总线控制模块从第二外围卡接收通信通知信号。 通信通知信号不干扰第一外围卡和第一驱动器模块的通信。 总线控制模块响应于通信通知信号而在第一和第二模式之间切换总线。

    • A host includes an operating system segmented into a user space and a kernel space with a driver. The user space stores a firmware file and the kernel space includes memory. The driver is stored in the kernel space and performs download cycles to download the firmware file to the memory. The device driver, during a first download cycle, transfers a first block of data to the memory. During each download cycle performed subsequent to the first download cycle, the driver is configured to: identify first and second segments of the memory, where data including the first block of data was stored in the first segment during a previous download cycle; copy the data including the first block of data from the first segment to the second segment; and transfer a block of data of the firmware file, not previously stored in the memory, to the second segment.
