System on Real-time Data Acquisition and Signal Processing System Based on Internet/Intranet Oriented DSP and Embedded Technologies

To realize net-based real-time communication and long distance diagnose,an embedded main architecture of real-time data acquisition and signal processing system based on TCP/IP is proposed and analyzed. And design and realization of the data communication system,which is based on Internet/Intranets including master CPU(ARM)of net managing,slave CPU(DSP)of data processing and their interface both in software and hardware are also presented.By using ARM and DSP master-slave system,embedded LINUX OS and reasonable multi-task-assigned mechanism,the demand for real-time and data communication speed of network are guaranteed.
