Abstract: This application provides an accumulator, a multiplier, and an operator circuit, and relates to the field of electronic technologies, to reduce an area and power consumption of the accumulator. The accumulator includes W compressor layers, where W is an integer greater than or equal to 1. The W compressor layers include at least one first compressor layer. In an input array of each first compressor layer, a first array includes a plurality of positive-phase bits, and a second array includes a plurality of negative-phase bits. Each first compressor layer includes a first compression circuit configured to compress the first array and a second compression circuit configured to compress the second array. To be specific, bits with different phases in the input array of each first compressor layer are compressed by different compression circuits.

Abstract: A multiplier implements multiplication of a first value and a second value, and includes P precoders, P encoder groups, and a compressor, where each precoder is configured to: precode at least two bits in the second value, to output a selection signal group; each encoder group is configured to: encode the first value and a selection signal group output by a precoder corresponding to the encoder group, to output a partial product item; the P encoder groups include a first encoder group, a first encoder of the first encoder group is configured to: encode a first selection signal group, a least significant bit in the first value, and a first sign bit, to obtain a first partial product and a first output sign bit, the first selection signal group is a selection signal group output by a first precoder, and the first precoder corresponds to the first encoder group.

Abstract: Some embodiments of the disclosure provide an ultra-low temperature phase change gel including a phase change matrix, a temperature regulator and a nucleating agent. In some embodiments, the phase change matrix is used as a host material for phase change to store and release cooling capacity, the temperature regulator is used for regulating the phase change temperature of the phase change matrix, and the nucleating agent is used for reducing a supercooling degree of the phase change matrix. The phase change matrix includes a temperature control material and water. The temperature control material includes sodium silicate, dipotassium hydrogen phosphate and aluminum sulfate, and the temperature regulator comprises polyethylene glycol. The nucleating agent includes a composite material formed by free radical polymerization of a reaction monomer and a macroinitiator. The composite material includes polyacrylic acid grafted with silica hybrid nano particles.

Abstract: This invention relates to a composite material comprising a core comprising an organosilica such as a polyhedral oligomeric silsesquioxane (POSS) and a functionalized elastomeric polymer such as poly(n-butyl acrylate) bonded onto said core. The elastomer is preferably functionalised with an amine moiety. The present invention also relates to a polymer comprising a resin such as Bisphenol A diglycidylether (DGEBA) and the aforementioned composite material, and a method for making the composite material. The composite material can improve both the material strength and material toughness of the polymer into which it is mixed.
