Abstract: The power consumption reduction is one of the core techniques in designing the portable intelligence instruments based on embedded microprocessor unit (EMPU). Through the case in designing the portable ambulatory ECG monitor based on EMPU, this paper presents the power consumption reduction methods and their application. These methods include electronic device selection; system design by the concept of minimum set of components, redundancy-restraining technique, software application for hardware; appropriate structure of memory; proper pattern of decoder and A/D converter working; proper pattern of system working and program running. Experimental results indicates that it reduces power consumption effectively. And it can be applied to the design of other portable intelligence instruments based on EMPU.
Key words: embedded microprocessor unit    power consumption reduction    minimum set of components
