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 method for preparing a color masterbatch with a natural dye is disclosed. The new method uses a phase change material tetradecane as one of the solvents to extract the natural dye, the extracted natural dye as a core material, and polybutylene succinate as a wall material to microencapsulate the natural dye containing the phase change material by a solvent evaporation method to prepare natural dye microcapsules, then melt-blends with a carrier resin, extrudes and granulates to obtain the color masterbatch with the natural dye. The microencapsulation improves the thermal stability of natural dye and compatibility with carrier resin The obtained color masterbatch with natural dye has excellent heat resistance, and the fabric obtained after spinning with it has good color fastness to hot pressing.
