    摘要： Apparatus and methods for USB hosts and USB devices to dynamically switch roles such that a product which initially operates as a USB host may instead operate as a USB device and vice versa. Products such as smartphones and tablets which initially operate as USB devices may dynamically switch roles to become USB hosts. Similarly, products such as PCs and in-vehicle infotainment systems which initially operate as USB hosts may dynamically switch roles to become USB devices. Dynamic USB role switching is permitted in a variety of topologies including those in which a direct connection exists between a host and a device as well as those in which a USB hub is present. In addition, such dynamic role switching may be performed in topologies which incorporate widely used USB Type A connectors and cables, thus avoiding the need for a special connector or cable.

    摘要： An active USB device and a method for switching an operating mode thereof are provided. In the method, a USB devices is connected to a first host device, and the USB device is in a compound device multi-port mode; the USB device is disconnected from the first host device and the USB devices keeps in the On state; upon detection disconnection of the USB device to the first host device, the USB device switches from the compound device multi-port mode to the single compact disc mode. According to the method for switching the operating mode of the USB device in the disclosure, the USB device can install driver without distinction and completely in various complicated application environments, thereby increasing user experience.

    摘要： Method for detecting presses on buttons of an electronic device with a reduced number of General Purpose In/Out (GPI/O) ports includes a number of the GPI/O ports The number of the buttons is greater than the number of the GPI/O ports. A proportion of the buttons are each coupled between one of the I/O ports and ground, and the remaining proportion of the buttons are each coupled between any two of the I/O ports. The GPI/O ports are set to work in a first working state or in a second state to provide a first signal or second signal respectively. When a signal provided by a GPI/O port working at the first working mode changes, the method determines which one of the buttons has been pressed.

    摘要： A data storage device having non-volatile solid state memory permits efficient access by permitting multiple pending commands from a host device. A controller in the data storage device stores information about each command from the host device, and determines which stored command, if any, is presently able to be performed based on the portion of the non-volatile memory and the type of access of the command. The data storage device provides reduced access delays, improves read/write throughput, and avoids the cost of additional memory in the data storage device, by allowing accesses to idle portions of memory to proceed, and by signaling the host device when the data storage device is able to accept data to be written to portions of the non-volatile memory already active due to a previous command.

    摘要： A Multi-Media Card (MMC) Single-Chip Flash Device (SCFD) contains a MMC flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. An initial boot loader is read from the first page of flash by a state machine and written to a small RAM. A central processing unit (CPU) in the microcontroller reads instructions from the small RAM, executing the initial boot loader, which reads more pages from flash. These pages are buffered by the small RAM and written to a larger DRAM. Once an extended boot sequence is written to DRAM, the CPU toggles a RAM_BASE bit to cause instruction fetching from DRAM. Then the extended boot sequence is executed from DRAM, copying an OS image from flash to DRAM. Boot code and control code are selectively overwritten during a code updating operation to eliminate stocking issues.
