Recent point cloud recognition (PCR) tasks tend to utilize deep neural network (DNN) for better accuracy. Still, the computational intensity of DNN makes them far from real-time processing, given the fast-increasing number of points that need to be processed. Because the point cloud represents 3D-shaped discrete objects in the physical... [Read More]

Due to the restricted on-chip computing capability for deep neural network (DNN) processing, high-definition video recognition (VOR) task is not easily achievable as a real-time task in a consumer SoC. Despite the fact that many accelerators have been proposed for fast VOR, they remain isolated from a video decoder’s inherent... [Read More]

Nowadays high-resolution (HR) videos have been a popular choice for a better viewing experience. Recent works have shown that super-resolution (SR) algorithms can provide superior quality HR video by applying the deep neural network (DNN) to each low-resolution (LR) frame. Obviously, such per-frame DNN processing is compute-intensive and hampers the... [Read More]

Nowadays, high-definition video object recognition (segmentation and detection) is not within the easy reach of a real-time task in a consumer SoC due to the limited on-chip computing power for neural network (NN) processing. Although many accelerators have been optimized heavily, they are still isolated from the intrinsic video compression... [Read More]

To tailor for DNN (Deep Neural Network) acceleration, GPU has migrated to new architectures such as NVIDIA Volta and Tur- ing that incorporate dedicated Tensor Cores. Although good at GEMM (generic matrix-matrix multiplication), Tensor Cores still have inefficiency facing convolutions with certain layer structures. This paper proposes a GPNPU (General-Purpose...

Quantization is an effective technique for Deep Neural Network (DNN) inference acceleration. However, conventional quantization techniques are either applied at network or layer level that may fail to exploit fine-grained quantization for further speedup, or only applied on kernel weights without paying attention to the feature map dynamics that may...

Deep neural networks (DNNs) have gained a strong momentum among various applications. The enormous matrix-multiplication exhibited in the above DNNs is computation and memory intensive. Resistive Random-Access Memory crossbar(RRAM-crossbar) consisting of memristor cells can naturally carry out the matrix-vector multiplication. RRAM-crossbar based accelerator therefore has two orders of magnitude of... [Read More]
