【摘要】 通用串行总线(USB)以其快速高效、即插即用及多设备类等特点成为目前应用最为广泛的计算机外设总线。USB固件程序开发是USB系统设计的重点内容,它直接影响到USB系统的数据传输速度。以基于TMS320C6747的声音采集系统为例,简单介绍了固件程序开发的目标和TMS320C6747芯片USB模块的硬件资源,并详细阐述了USB系统的固件程序编写流程及相关代码,以实现该系统与PC机之间的高速数据通信。

【Abstract】 With the fast,efficient,plug-and-play and multi-device class characteristics,Universal Serial Bus(USB) has become the most widely used computer peripheral bus.USB firmware development is the focus of the USB system design.It will directly affect the data transmission speed of the USB system.Take voice acquisition system based on TMS320C6747 for example,the target of firmware development and the hardware resources of the USB module in TMS320C6747 are introduced and the USB firmware programming process and related code in detail are described to realize the high speed data communication system between the voice acquisition system and PC.
