摘　　要：本文设计了一种基于Ti公司低功耗DSP芯片和Cygnal低功耗的混合信号系统级单片机心电数据处理传输电路,它能够实时采集、处理、用移动网传输心电数据。该电路CPU单元为核心,主要由DSP、CPU、ECG三个单元和其它辅助单元组成。该电路具有体积小、便于携带、功耗低、可使用电池供电的特点,适用于要求心电数据采集、处理和传输的小型或便携仪器上使用。A circuit of processing and transfering ECG based on TMS320C54X series DSP and Cygnal low power consumption mixedsignal micro-controller is introduced. The circuit is used to collect, process and transfer ECG by mobile net. The circuit which core is CPU unit is composd of three main units （DSP, CPU, and ECG） and other assistant units. The circuit is characterized by small size, portability, low power consumption and being powered by batteries, so it can be used in the small and portable devices for collecting, processing and transferring ECG.
