A received data processing method in a wireless communication between devices that support a bluetooth wireless technology is provided. The method for processing data received through a wireless channel, in a communication device that supports bluetooth wireless communication, includes the steps of (a) a bluetooth module receiving data through a wireless channel, (b) the bluetooth module informing a bluetooth host that data received through a universal serial bus (USB) exists in the bluetooth module, and (c) the bluetooth host reading the data received by the bluetooth module in the step (a) through the USB when the bluetooth host is informed that received data exists in the step (b). According to the received data processing method, it is possible to prevent overhead from occurring due to unnecessary request for data by the bluetooth host generating request for data through the USB only when the received data exists in the bluetooth module. Accordingly, it is possible to minimize load of the bluetooth host and to improve data receipt bandwidth in a bluetooth host controller interface (HCI) universal serial bus (USB) transport layer. Also, the entire USB transmission speed is increased since request for data can be generated at the point of time at which data is received.

Provided is a communication interface between an NFCH and an NFC device and a method for controlling an NFC HCI. In the method, a command message is transmitted from the host to the device. The command message includes one of recording data, reading data of the device, requesting the device to transmit predetermined data, and setting the device. A response message informing a performance result of a relevant command is transmitted from the device to the host in response to the command message. After that, an event message is transmitted from the device to the host when needed.

A data storage device has a host controller interface, a plurality of microprocessor units each having a portion of random access memory (RAM) dedicated thereto, a plurality of Flash device configurations each having dedicated bus connections to individual ones or multiples of the microprocessor units, and a dataflow controller accessible to the host controller interface for managing access to the Flash device configurations.

Method for streaming data over a plurality of data links formed between a Bluetooth® master device and a plurality of Bluetooth® slave devices includes constructing a vendor specific command host controller interface (HCI) packet, sending the vendor specific command HCI packet to a host controller of the Bluetooth® master device, and constructing at least one baseband packet addressed to each slave device of the plurality of slave devices. The vendor specific command HCI packet includes a plurality of ACL headers, a plurality of L2CAP headers, and a payload. A Bluetooth®-enabled device configured to stream data over a plurality of data links formed between a plurality of slave devices includes a Bluetooth®-enabled host adapted to construct a vendor specific command host controller interface (HCI) packet, an HCI transport layer and a host controller adapted to receive the vendor specific command HCI packet over the HCI transport layer.

A system and method using ANT and / or ANT+ protocols for one or more ANT and / or ANT+ applications. The system can include a Bluetooth interface and a Host Controller Interface (HCI) that are configured to process incoming and outgoing ANT and / or ANT+ messages from / to one or more ANT and / or ANT+ enabled devices. The ANT and / or ANT+ messages can be communicated to one or more ANT and / or ANT+ enabled devices utilizing a Bluetooth transceiver. The Bluetooth interface and the HCI can be configured to wrap one or more ANT and / or ANT+ messages with a header and / or to remove a header from one or more wrapped ANT and / or ANT+ messages. The header can be an HCI compatible header.

Universal Serial Bus (USB) is a Master / Salve or Host / Device system in which there is only one host and one or more devices connected by cables to the host. To connect a USB device to a different host controller (say another PC), the user unplugs the USB cable and establishes the connection physically by plugging the cable into the new host controller interface. Certified Wireless USB (CWUSB), a logical extension to the USB, preserves the USB connection model, except that the link between the host and the device is now using a wireless technology. A wireless device is usually connected to only one wireless host at a given point of time, even though several wireless hosts may be co-located in the same physical neighborhood. The connection between the wireless host and device is initiated by the device. A device usually selects a wireless host from a stored set of known hosts that have established a trusted relationship with the device. If more than one wireless host is operating in the same neighborhood, there is no well known established procedure for the device to select a particular wireless host to establish a connection.

Methods and systems for queuing transfers of multiple non-contiguous address ranges within a single command are disclosed. Embodiments of systems include system processors, memory to store data and executable software, and storage devices to receive transfer commands stored in system memory. A host controller interface driver is executed by one or more system processors and collects multiple non-continuous address ranges from storage-device transfer requests and records starting addresses and quantities of data to transfer for each non-continuous range in a tagged command list. It records the number of address ranges in the tagged command list, and a tagged-transfer opcode in a command, and stores the command and the tagged command list in a command table for the storage device. It records a base address for the command table in memory and an offset for the tagged command list into a command header, which is stored in a command queue.
