摘要
数字信号处理器(DSP)的高速运算性能使它在数字信号的处理上有着独一无二的优势,但是通常数字信号的数据量非常庞大,需要一种非常方便、高速的接口来实现与计算机的接插。而通用串行总线(USB)接口具有许多其它总线无法比拟的优点。在阐述系统硬件、软件实现方案的基础上,针对固件和驱动程序开发中的关键技术进行了深入的分析。
The DSP＇s high-speed operation function makes it have the unique advantage on the processing of the digital signals. But usually the data of the digital signals are so huge that convenient interface of high speed is needed to connect with PC machine. The USB interface has many advantages that other bus can＇t compare to. Some key techniques are furtherly discussed in detail on the firmware and the driver software after the design of hardware and software of the system are proposed.
