An SOPC-based Design and Implementation of Neural Monitoring System

Neurosurgery is widely used in clinical application.As the key neurosurgery assistive technology for neurosurgery,neural monitoring is used to real-time accurately monitor neural state and effectively prevent nerve injury.In this paper,an SOPC-based neural monitoring system is presented.This system integrates analog circuits with digital circuits and cooperate hardware circuits with NIOS II embedded software.To optimize the system,ping-pong operation,serial to parallel conversion and pipeline are employed.The function of system is tested by embedded logic analyzer.It is showed that the system sequence,data conversion and transmission are normal.The whole design is completed on a Cyclone III-based development board,DE 0.The resource consumption is 7 516 logic elements and the maximum hardware-work-frequency could achieve 125.74 MHz while the software-work-frequency is 119.76 MHz.
