Abstract
In recent years, the number of sensor systems has been rapidly increasing with the spread of IoT. This paper proposes an FPGA-based CoAP server aiming at a high degree of power-performance ratio. CoAP is a Web transfer protocol designed for IoT systems. A general sensor node has a processor to receive and process data from a sensor, and to transport data to the outside. However, power consumption of software processing is high, compared with hardware processing. Therefore, we propose an approach with using only an FPGA to process data from sensors. In this work, we design and implement a CoAP server which responds to GET, DELETE, and PUT requests on the FPGA. Empirical performance evaluation results of the proposed system are also presented.
