Multi-channel synchronal real-time data acquisition system based on FPGA

With the application of data acquisition system in power systems, a novel real-time, multi-channel synchronal high speed data acquisition system based on FPGA is designed in the paper. The system integrates many functional modules into a piece of FPGA and forms a programmable system, the modules(such as A/D converter, dual-port RAM and so on) are controlled by the FPGA. The hardware block diagram is presented, and the structure of each functional module and control logic are described emphatically. The feature of the system is stable, strong real-time, highly integrated, expandable and general.
