The GL620USB provides a single-chip solution for connecting two or more PCs via their USB ports. According to USB protocol, the PC is the host and the device is a slave, where the host initiates all the USB traffic and the slave responds to the host’s requests. In other words, a host cannot talk to another host via USB protocol; instead, a host can only talk to one or more devices. The GL620USB’s patent-pending architecture overcomes the USB inherently incompatibility of connecting two or more PCs by providing two independent USB transceivers and
SIEs for each host, i.e., data can be transferred in both directions simultaneously.
System Diagram
We provide application program to share file between 2 PCs. This application is easy to install for end users. Besides, the file transfer rate of the application program (combined with GL620USB) is up to 8.6Mbps. With this file transfer application, PCs can share files on all local drives, such as hard drive, floppy, CD-ROM and network drives.
The GL620USB-Lite file transfer function can be integrated with the following form factors:
? USB standalone cable
? USB standalone hub
? USB monitor with hub
? PC host
4. Functional Description
Block diagram of GL620USB-Lite
The GL620USB-Lite is equipped with two full-speed USB ports, and each port has four endpoints to provide different functions as follows: - Endpoint 0: control transfer - Endpoint 1: bulk-read transfer - Endpoint 2: bulk-write transfer - Endpoint 3: interrupt transfer
Two 8-bytes FIFO and four 64-bytes FIFO are built in the device as follows: -
Left 8-byte FIFO: provide a pipe to link left endpoint 0 and right endpoint 3. For example, if left host wants to communicate with right host, left host can issue a no data control transfer and the setup command will be stored
D+
D-
- Right 8-byte FIFO: provide a pipe to link right endpoint 0 and left endpoint 3.
- Left 64-bytes DATA0/DATA1 FIFOs: provide a pipe to link left endpoint 2 and right endpoint 1. For example, if left host wants to transfer data to right host, left host can issue bulk write transfer and the payload will be stored in the left 64-byte FIFOs. Right host can request a bulk read transfer to get the data from left host.
- Right 64-bytes DATA0/DATA1 FIFOs: provide a pipe to link right endpoint 2 and left endpoint 1.
