Convolutional neural networks can't, however, be implemented on portable FPGA devices because to their high computing, storage, and energy needs. In this paper, we propose a generic solution for image dehazing from CNN models to mobile FPGAs. The proposed solution designs lightweight network using depth-wise separable convolution and channel attention mechanism, and uses an accelerator to increase the system's processing efficiency. We implemented the entire system on a custom and low-cost FPGA SOC platform (Xilinx Inc. ZYNQ$^{TM}$ XC7Z035). Experiments can conclude that our approach has compatible performance to GPU-based methods with much lower resource usage. Keyphrases: Accelerator, FPGA-based dehazing, separable convolutional neural network
