基于DSP的USB接口设计

USB Interface Design Based on DSP

在数据采集系统中,利用DSP作为微处理器对采集到的数据进行处理,再通过USB接口将处理过的数据传输到PC机上进行存储,这样可以实现数据的快速采集与存储。采用TI公司的TMS320F2812作为微处理器控制芯片,并使用Philip公司的ISP1581作为USB收发控制芯片,利用两者的速度优势,能够实现DSP与PC机之间的高速数据传输,从而使得大量数据的快速,实时的采集、处理与存储成为可能。

In data acquisition system, using DSP to process the collected data, and then transfering the processed data to PC by USB interface,this can archive fast data acquisition and storage. Selecting TI Corporation＇s TMS320F2812 for microprocessor control chip and Philip Corporation＇s ISP1581 for USB receiver/transfer control chip,it can achieve the high speed data transfer between DSP and PC by their speed,therefore,it can realize high speed,real -time collection,process and storage for mass data.
