Abstract: Disclosed herein is a method of stripping a strong reflection layer based on deep learning. The method establishes a direct mapping relationship between a strong reflection signal and seismic data of a target work area through a nonlinear mapping function of the deep neural network, and strips a strong reflection layer after the strong layer is accurately predicted. A mapping relationship between the seismic data containing the strong reflection layer and an event of the strong reflection layer is directedly found through training parameters. In addition, this method does not require an empirical parameter adjustment, and only needs to prepare a training sample that meets the actual conditions of the target work area according to the described rules.

Abstract: Some embodiments of the present disclosure provide a chip accessing method, a security controlling module, a chip and a debugging device. A chip accessing method is applied to a chip, including: after a debugging device is detected, triggering security authentication on the debugging device in which a security card that pre-stores a first private key is inserted; acquiring from the debugging device a first authentication information generated by the debugging device at least based on the first private key; determining whether the debugging device is authenticated according to the first authentication information; and enabling a debugging interface when the debugging device is authenticated to allow the debugging device to access the chip through the debugging interface. The embodiments in the present disclosure are advantageous for improving security, convenience, and flexibility when the debugging device is accessing a chip.
