摘要
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,而U SB以灵活的运用,统一的标准,在各种设备上的应用越来越广。以T I公司新型DSP芯片TM S320F 2812和CYPRESS公司的U SB控制芯片CY 7C 68001为例,介绍了一种U SB和DSP芯片之间的接口方法,提供了一个灵活的通讯接口,解决了传统励磁控制器数据传输的带宽问题,并给出了固件开发、驱动开发和应用软件编写的基本方法。
The great high-speed operation capability of DSP make it predominate over digital signal trans action, and USB applys at kinds of equipments more and more widely as it＇s agility and uniform criterion. This paper gives a solution of the application of USB for an excitation controller based on DSP. It compares the solutions of USB interface, selects a fit one, and discusses the hardware solution, the firmware solution, the driver software solution, and the application software solution.
