Abstract: An artificial intelligence inference computing device contains a printed circuit board (PCB) and a number of electronic components mounted thereon. Electronic components include a wireless communication module, a controller module, a memory module, a storage module and at least one cellular neural networks (CNN) based integrated circuit (IC) configured for performing convolutional operations in a deep learning model for extracting features out of input data. Each CNN based IC includes a number of CNN processing engines operatively coupled to at least one input/output data bus. CNN processing engines are connected in a loop with a clock-skew circuit. Wireless communication module is configured for transmitting pre-trained filter coefficients of the deep learning model, input data and classification results.
