Objective To design and implement a set of EEG acquisition and processing system based on RHA2116 acquisition chip. Methods The system was composed of the EEG electrode, RHA2116 acquisition chip, ARM S3C6410 microprocessor, AD7980 analog-digital conversion chip and PC. The PC sent control command to ARM microprocessor through JLINK emulator, and then ARM microprocessor drove RHA2116 chip to acquire EEG signals after reading the command. The acquired data were transmitted to the upper computer by ARM microprocessor for processing and display.Results The system could acquire EEG signals at real time, and obtain could EEG results with data processing by the upper computer. Conclusion The system can be used for real-time EEG signal acquisition, and is worthy applying practically.
