Rapid Design Methodology for Accelerator-based Wireless Sensor Nodes in Structure Health Monitoring
Node-level signal processing becomes popular to reduce the data amount and power consumption of wireless sensor nodes. It puts more productivity challenges on the design flow, because various applications lead to different accelerators. In this paper, we proposed a rapid design methodology for accelerator-based sensor nodes (RAS design methodology). We evaluated RAS design methodology in a structure health monitoring (SHM) system and implemented a sensor node with a radix-2 8-point FFT accelerator using ANSI C. Several C-level optimizing techniques are used to further improve the performance. Measured results show that compared with the software solution, RAS design achieves up to 40x times speedup while the design time is shorten from several weeks to days.
