无线和有线USB接口共存的数据传输系统

Data Transmission System with Wireless and Wired USB Interface

介绍一种基于DSP的无线和有线USB接口的数据传输系统,实现无线USB和有线USB之间的通信,将无线USB数据传输到PC机,解决无线USB设备向PC机兼容问题。该系统可实现无线USB的62.5kbps的数据传输速率,有线USB的实际传输速率达到100Mbps,可以实现高速实时的数据传输。由于以DSP为核心处理器,适合于语音和控制系统的应用。该系统具有小型化、低功耗、使用方便等特点。

A data transmission system with wired and wireless USB interface is introduced. Communication between wireless and wired USB is realized, and wireless USB data is transferred to PC; therefore, compatibility issue is resolved. The system implements wireless USB at 62.5 kbps and USB at 100 Mbps. The system is compact,low-powered and easy to use. With DSP as core proceessor, it is suitable for voice and control applications.
