Abstract:

CNN-based super-resolution methods achieve great performance but come with high bandwidth requirements. This paper proposes a bandwidth efficient CNN-based architecture for super resolution supporting up to Full HD images at 60 fps. The bandwidth efficiency is achieved by layer fusion with data reuse scheduling and dynamic quantization. To maintain a high utilization of processing elements, the deconvolution operation is decomposed into a several convolution operations. The proposed architecture provides a 94.8 % bandwidth reduction. Compared to the software implementation, less than 1 % performance drop is induced in this VLSI implementation. The enables the proposed architecture to obtain state-of-the-art accuracy compared to existing super-resolution hardware implementations.
