Abstract: | New sensors are required to be small, cheap, and smart. This paper deals with intelligent sensors embedded in a single chip: a VHDL model of an IEEE1451.2 Smart Sensor is proposed to obtain a portable STIM block suitable for customizable compact solutions and allowing low-cost, large-scale production. In order to evaluate performances of the proposed model, working prototypes have been built and some tests have been carried out in a real case (chemical detection sensors). The proposed VHDL model has been compared with traditional, software-based, microcontroller solutions showing that a timing performance improvement greater than 50% can be obtained. Finally, to exemplify effectiveness of a portable VHDL model, a single-chip sensor with USB interface and integrated IEEE1451 structures has been realized and experimentally characterized |
