  • Publication number: 20220083313
    Abstract: The present invention discloses an error unbiased approximate multiplier for normalized floating-point numbers and an implementation method of the error unbiased approximate multiplier. The error unbiased approximate multiplier includes a symbol and exponent bit module, a mantissa approximation module and a normalization module, wherein the symbol and exponent bit module processes symbolic operation and exponent bit operation of the floating-point numbers; the mantissa approximation module obtains a mantissa approximation result under different accuracy requirements by summing a result of multilevel error correction modules; and the normalization module adjusts an exponent bit according to the operation result of the mantissa and processes the overflow of the exponent bit to obtain the final product result.

  • Patent number: 11030528
    Abstract: A convolutional neural network pruning method based on feature map sparsification, which relates to how to compress the convolutional neural network to reduce the number of parameters and amount of computation so as to facilitate actual deployment, is provided. In the training process, by adding regularization to the feature map L1 or L2 after the activation layer in the loss function, the corresponding feature map channels have different sparsity. Under a certain pruned ratio, the convolution kernels corresponding to the channels are pruned according to the sparsity of the feature map channels. After fine-tune pruning, the network obtains new accuracy, and the pruned ratio is adjusted according to the change of accuracy before and after pruning. After multiple iterations, the near-optimal pruned ratio is found, and pruning is realized to the maximum extent under the condition that the accuracy does not decrease.

  • Patent number: 10673475
    Abstract: The disclosure provides a transmitter of a communication system using hybrid digital/analog beamforming and configured to perform digital pre-distortion (DPD). In an exemplary embodiment in accordance with the disclosure, the transmitter may generate a plurality of scrambling sequences. The transmitter may comprise a plurality of combining modules to receive a combined feedback signal. The transmitter may use the plurality of scrambling sequences to recover the signals output by the antenna arrays from the combined feedback signal. Thus, the transmitter may perform DPD for each antenna array.
