Abstract
SoPC technology based on FPGA is a flexible and efficient countermeasure for system-on-chip, which provides a new way to develop high-precision geoelectric data acquisition devices. This paper introduces the application of SoPC technology to research and design of an A/D conversion controller which complies with the time sequence of CS5372, a module converting the serial data to parallel one. a resampling FIR digital filter using Matlab and DSP Bulider, a NIOS II Soft IP Core integrated by Quartus II and a PC software designed with LabVIEW. Under the application of equipments mentioned above, Cyclone chip, which replaces expensive CS5376, can be used to realize the acquisition of the high-precision geoelectric data. As the result shown, the use of the technology of SoPC can greatly improve the cost-effectiveness of high-precision geoelectric data acquisition devices and also can integrate the digital parts of geoelectric data acquisition devices into a chip, which also provide an effective way to solve problems under the complex geoelectric conditions.
