Abstract


In recent years, with the rapid development of SOPC technology, based on the technology embedded product after another, covered by the scope of more and more widely. Most of the medical monitoring system processor MCU, DSP, or PLC, because these processors monitoring accuracy, real-time requirements and system miniaturization and other restrictions, have begun to not at full requirements of FPGA-based reconfigurable SOPC technology become an inevitable choice. The main work of this paper is to use SOPC technology research of the medical electronic information processing system. The topics to study ECG (ECG) acquisition process, for example, details the design process of the entire physiological signal processing module. The design of the system is divided into three steps: The first step is a physiological signal acquisition and pre-processing. Acquisition of physiological signals and the signal at this stage is primarily for pre-filtering relates to ± 5V power supply circuit, the preamplifier circuit, 0.03 to 130Hz band-pass filter circuit, amplifying circuit and A / D converter circuit, ECG after treatment of these modules can be input to the programmable controller further processing. The second step is to design the FPGA functional modules to complete the design of the system's hardware. Design based on the SOPC system hardware FPGA embedded IP soft core clock frequency of 50MHz the the ECG control module design, display mode to 640 * 480 VGA control module design, the design of the system clock, keyboard control design, as well as some auxiliary function modules add. Wherein the the ECG control module and the VGA control module respectively, to achieve the digital filtering of the digital ECG signal waveform output, heart rate calculation and the control of the ECG signal in the VGA output. The third step is to add a software program in a good hardware system has been set up to achieve the overall operation of the system. In the design of the software according to the system requirements, design completed five tasks, respectively, for the service request, the waveform display, session, save the clock display. Where tasks Server in the external network connection request, will accept the request and creates the task of sending and receiving; when the storage or playback request, the task Save will also create a storage or playback tasks. Based on the the SOPC technology medical electronic information processing system has the advantages of shorter product design cycles, and the development of low-cost, risk, performance of system reconfiguration easy system upgrade, it is bound to be widely used in future medical monitoring field.
