A lead-free metallic halide memristor is disclosed. The lead-free metallic halide memristor comprises a first electrode layer, an active layer and a second electrode layer, of which the active layer is made of a metallic halide material. Experimental data have proved that the lead-free metallic halide memristor possesses synaptic plasticity because of showing characteristics of short-term potentiation, short-term depression, long-term potentiation, long-term depression during the experiments. Therefore, the lead-free metallic halide memristor has significant potential for being used as an artificial synaptic element so as to be further applied in the manufacture of a reservoir computing chip. Moreover, experimental data have also proved that the lead-free metallic halide memristor also shows the characteristics of multi-level resistive switching, whereupon the lead-free metallic halide memristor can be further used as analog non-volatile memory so as to be further applied in the manufacture of a neuromorphic computing chip.

For solving the defect that a hardware clock of a serial peripheral interface bus has to cooperate with slower software-simulated clocks used by a microprocessor while applying serial peripheral interface buses on a large-scale touch panel, a programmable logic device is used as a bridge of communicating information between the micro processor and sensors. Therefore, the microprocessor no longer has to take execution time to simulate serial peripheral interface buses by software, and is able to program hardware clocks of each of the serial peripheral interface buses according to speed requirements of different sensors, so that sensing signals of a plurality of sensors may be integrated on a touch device having the large-scale touch panel, and a processing speed of the touch device in processing the sensing signals may be optimized as a result.
