Abstract: A multi-task joint perception network model and detection method for traffic road surface information can simultaneously detect a lane line and a drivable area. A coordinate attention mechanism is integrated into a traditional feature extraction network to ensure that a feature extraction effect is enhanced while a calculated amount is not increased. In a neck network, a dilated convolution residual module is proposed to enhance performance of prediction of details by the network, and a decoder part shares features of the drivable area into lane line detection to enhance a lane line detection effect under complex road conditions. In a training stage, there is provided a alternating optimization training method to improve integral segmentation performance of the model. The multi-task joint perception network model and detection method realizes quite high accuracy and excellent speed performance in a challenging BDD100K dataset.

Abstract: Methods and apparatuses are provided for alignment of hardware and software Vsync signals through filtering out delayed timestamp signals in a hardware timestamp signal used to generate the software Vsync. The alignment may occur when a display client is operating in a video mode but not a command mode. A compositor or processing unit may receive a hardware Vsync signal from a display using a video mode, generate a hardware timestamp signal based on the hardware Vsync signal, determine a delay for a pulse in the hardware timestamp signal based on a delay for a set of previous frames, determine whether the delay for the pulse is over a threshold, and control rendering and transmission of a frame to the display based on the delay for the pulse being over the threshold. Thus, accurate Vsync signal synchronization may occur.

Abstract: A reconfigurable PUF device based on fully electric field-controlled domain wall motion includes a voltage control layer, upper electrodes, a lower electrode, antiferromagnetic pinning layers, and a magnetic tunnel junction (MTJ). The MTJ includes, from bottom to top, a ferromagnetic reference layer, a potential barrier tunneling layer and a ferromagnetic free layer. In the device, an energy potential well is formed in a middle portion of the ferromagnetic free layer by applying a voltage to the voltage control layer to control magnetic anisotropy, and a current is fed into either of the upper electrodes to drive generation of the magnetic domain walls and pin the magnetic domain walls to the potential well. After the voltage is removed, the potential well is lowered so that the magnetic domain walls are in a metastable state, thereby either a high resistance state or a low resistance state is randomly obtained.
