A high-speed data transmission device and method based on usb

Abstract

The invention discloses a USB (universal serial bus)-based high-speed data transmission device and a USB-based high-speed data transmission method. The USB-based high-speed data transmission device comprises a first microcontroller and a second microcontroller which are provided with USB interfaces. GPIFs (general programmable interfaces) are respectively arranged on the first microcontroller and the second microcontroller, the first microcontroller and the second microcontroller are connected with each other by the GPIFs and are respectively connected with two computers by the USB interfaces on the first microcontroller and the second microcontroller, data exchange needs to be carried out on the two computers, and the two computers are provided with device drivers; each of the first microcontroller and the second microcontroller comprises a buffer. Data can be directly transmitted between the two computers by the data transmission device, so that large quantities of data can be directly and quickly copied between the computers for users and can be shared by the users without extra mobile storage media. The USB-based high-speed data transmission device and the USB-based high-speed data transmission method have the advantages of low cost, high transmission speed, simple structure and the like.

Description

technical field [0001] The invention belongs to the technical field of data communication, in particular to a USB-based high-speed data transmission device and method. Background technique [0002] Universal Serial Bus (USB) is a serial bus standard that connects computer systems and external devices. It is also a technical specification for input and output interfaces. It is widely used in information communication products such as computers and mobile devices, and has been extended to Photographic equipment, digital TV (set-top box), game consoles and other related fields. At present, there are mainly two ways to back up or share data between two computers, first, through the network; second, using a mobile storage device. The first method must be through the network card, but the current upper limit of the five types of lines supports 100Mbps, and the second method is through the mobile hard disk, which is currently the most used and faster way. The first method is limi...

AI Technical Summary

Problems solved by technology

The first method must be through the network card, but the current upper limit of the five types of lines supports 100Mbps, and the second method is through the mobile hard disk, which is currently used more and faster.

The first method is limited by the transmission rate of the five-category line, and may also be limited by the transmission rate of routers, switches and other LAN devices, so it is relatively slow when transmitting large amounts of data, while the second method is not only limited by The speed of reading and writing mobile storage devices, and more importantly, it needs to go through an intermediary when performing data backup or sharing, so that there is one more process of reading and writing data

Currently, protocols with higher transfer rates on computers include Thunderbolt (20Gbps), USB2.0 (480Mbps), USB3.0 (5Gbps), USB3.1 (10Gbps), SATA2, (3Gbps) SATA3 (6Gbps), PCI Express (up to 16Gbps), etc., but there is no device that enables data transmission between two computers to make good use of these high-speed protocols
