Abstract: A multiplier is configured to implement multiplication of a first value of M bits and a second value of N bits, and includes P groups of encoders and W layers of inversion compressors. Each group include N encoders and are configured to encode a part of bits in the second value, and a group selection signal and a symbol control input signal corresponding to the each group. The group selection signal and the symbol control input signal are generated based on a part of bits in the first value, and the P groups of encoders perform encoding to obtain P partial products. The W layers of inversion compressors are configured to compress the P partial products.

Abstract: A power management system includes a direct current-direct current DC-DC conversion circuit, a first control circuit, a charging circuit, an input port, and an output port. The input port is configured to receive an input voltage. The output port is configured to supply an output voltage to a load. The DC-DC conversion circuit is configured to charge the output port from the input port, to adjust the output voltage. The first control circuit is configured to: obtain a second feedback voltage of the output voltage from the output port, generate a first control signal based on the second feedback voltage and a second reference signal, and supply the first control signal to the charging circuit. The charging circuit charges the output port from the input port based on the first control signal, to supplementally adjust the output voltage.

Abstract: A multiplier is configured to implement a binary single-multiplication operation A[m1-1:0]×B[m2-1:0], or an accumulated sum operation of 2N binary multiplications A0[m3-1:0]×B0[m4-1:0]. The multiplier includes P precoders, Q groups of fusion coders, and a compressor. The P precoders and the Q groups of fusion coders are configured to code a first value and a second value in the single-multiplication operation or the multi-multiplication accumulated sum operation, and output a plurality of partial products to the compressor. The compressor may be configured to compress the plurality of partial products corresponding to the single-multiplication operation or the multi-multiplication accumulated sum operation to obtain two accumulated values.
