Real-time analysis of biomedical signals using a high speed DSP board

A real-time biomedical signal analysis system based on SHARC ADSP-21062 EZ-LAB board was examined in this paper. Installed as an embedded system on a PC workstation, the DSP board was tested for real-time performance in extracting features from respiration signals and classification among different respiration episodes, including apnea. Test results show that high performance DSP boards may be easily setup in a typical biomedical laboratory to perform and to be used effectively in heavy computation for a real-time application.
