Title The real-time video capture software design based on USB3.0 interface
Abstract
With the development of storage technologies and demanding high-definition video and the image of forcing improve data transfer speed, so USB 3.0 protocol came into being.USB 3.0 inherited the advantages of Plug and Play, easy expansion, interface simple , its theoretical bandwidth up to 5Gbps.The growing popularity of USB 3.0 and the expansion of application fields, the development of real-time video capture software and hardware-based USB devices also comply with the requirements of the times 3.0 interface.The main problem is to solve real-time video capture software design which based on USB 3.0 interface.
The task design uses a new generation of USB 3.0 Peripheral Controller Cypress CYUSB3014_BZX1 chip.Design uses USB 3.0 protocol in bulk transfer mode for high-volume data transfer.EZ-USB FX3 Slave FIFO uses a synchronous mode of operation in order to improve transmission efficiency.
According to the needs of the overall system design software program, completing the structure of the functional modules of software design. Object-oriented software platform in Visual Stdio2010 method, based on the MFC technology, multi-threading technology, and USB3.0 protocol specification complete system PC interface software (GUI) and a system control module design.
