Abstract

This paper proposes a Virtual Instrument Platform based on serial port communication.The system is composed of DSP part and PC part.We use DSP as a co-processor to sample and do some pretreatment.The PC platform is in charge of signal analysis and system control.The communication between the PC and DSP is based on the serial port.The paper analyzes the influence that the quality of the communication makes on the signal analysis.The result shows that the serial port is stable and fast,which is able to accomplish the work.
