Multi-mode electronic stethoscope implementation and evaluation using Dynamic Reconfigurable Design

Dynamic Partial Reconfiguration (DPR) is an efficient technique in terms of power, resources and performance in order to achieve varying user requirements. In this paper we have identified various modes of operation of electronic stethoscope and also studied several existing implementations. We propose a Dynamic Reconfigurable Design for the multi-mode electronic stethoscope with five operational modes. Implementations were performed on Virtex-5 XC5VLX110T FF1136 device. Comparative results were presented between the proposed method and the normal FPGA implementation method. Also the reconfiguration timings were analyzed and the results were compared with the ideal reconfiguration time of Virtex-5. The proposed Dynamic Reconfigurable design is able to achieve a reconfiguration time of 28.86 ms with the reconfiguration speed of 3.46 MB/sec.
