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 high-speed computing performance of digital signal processors (DSPs) gives them unique advantages in the processing of digital signals. However, digital data typically has a large amount of data and requires a very convenient and high-speed interface to interface with a computer . The universal serial bus (USB) interface has many other advantages of the bus. Based on the elaboration of system hardware and software implementation scheme, the key technologies in firmware and driver development are analyzed in depth.
