Abstract: The present invention relates to the technical field of central processing units (CPUs), and in particular to a fault-tolerant system with multi-core CPUs capable of being dynamically configured. The multi-core CPUs are three reconfigurable CPUs, the fault-tolerant system with multi-core CPUs is statically configured to be in a normal fault-tolerant mode, a reliable fault-tolerant mode or a performance mode by means of configuration of the three CPUs and then is switched between the normal fault-tolerant mode, the reliable fault-tolerant mode and the performance mode according to a mode switching command of a mode switching register, and finally, the three CPUs are correspondingly configured according to the mode to be switched.

Abstract: A processing apparatus includes a collection module and a training module, the training module includes a backbone network and a region proposal network (RPN) layer, the backbone network is connected to the RPN layer, and the RPN layer includes a class activation map (CAM) unit. The collection module is configured to obtain an image, where the image includes an image with an instance-level label and an image with an image-level label. The backbone network is used to output a feature map of the image based on the image obtained by the collection module.

Abstract: A method for preparing the modified polyester. The modified polyester segments include terephthalic acid segment, ethylene glycol diol segment and branched diol segment, in which the branched diol segment refers to a diol segment in which a branch is located on a non-terminal carbon in the glycol segment and the branch is a linear carbon chain having 5 to 10 carbon atoms. The method includes preparing terephthalic acid glycol ester through the esterification of terephthalic acid and branched diol using the concentrated sulfuric acid as the catalyst. Then get ethylene terephthalate through the esterification of terephthalic acid and ethylene glycol. After stirring and mixing the two, the modified polyester can be obtained through polycondensation reaction of a low vacuum stage and a high vacuum stage using the catalyst and stabilizer.
