Low complexity and power consumption design for pacemaker using shared MAC structure based on FPGA platform

Most of the critical issues of cardiac pacemakers and ICDs are the device size and power consumption problem. Because devices size for cardiac implant is limited, we always have to consider trade-off relationship between size and longevity. Accordingly, we proposed a MAC-sharing structure based on FPGA platform for small size and low power consumption. The MAC-sharing structure contains a single multiplier using a time division method, hence we reduce a system complexity and power consumption with this method. In this paper, we show the result of atrial fibrillation detection using the proposed structure based on a FPGA platform.
