This study proposes a smart chip and system design for detecting dental diseases and road defects using image processing. The system includes a low power consumption and miniaturization adjustable digital filter, an automotive FPGA system for recognizing road defects, and a dental disease automatic identification system based on a convolutional neural network. The medical auxiliary system includes an image analysis, an enhancement, a correction, and an artificial intelligence research. This study has achieved over 95% accuracy in identifying all dental diseases based on symptoms, with an increase in identification technology by 13.14% and 1.34%, respectively. In developing the embedded system for automobiles, the Xilinx ZCU104 platform and YOLOv3 are utilized for real-time pothole detection. The established system can perform real-time pothole detection on the FPGA platform at an execution speed of 27.8 FPS while successfully compressing 39.8% of the size of the real-time pothole detection system. Besides, this design employs temporary registers to store coefficients and realizes the digital filter structure of the finite impulse response through the usage of coefficients. The coefficient storage unit facilitates easy integration into other circuits, allowing for adjustable filter functionality by modifying the filter frequency band through software and firmware. This research creates an adjustable digital filter using a low-complexity algorithm and a pipelined architecture in terms of hardware. The chip is manufactured using TSMC 0.18-μm technology. The operating frequency of this chip is 50MHz, and its power consumption is 0.25 mW. The proposed chip design uses the simplification of the FIR calculation algorithm to cut the number of multipliers required by the overall structure in half. The chip core area and logic gate counts are 3,502.52 × 3,497.6 μm2 and 586,680, respectively.
