The Data Collecting And Processing System Based On DSP And USB

This paper focuses on the proposal of the data collection and processing system based on DSP (Digital Signal Processor) and USB (Universal Series Bus) and its performance. It accounts for,in detail,the content and performance of USB protocol with USB being the communications protocol,and DSP the central processor,and thus processing some basic digits on the basis of this data collection system. It is convenient to control collecting and processing the on-the-spot data through linking with the portable computer. In the end,the paper tells the practical procedure of applying the involved hardware and software to the system.
