Title:
MULTIMODE FUSION MULTIPLIER
Document Type and Number:
WIPO Patent Application WO/2021/196096
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronics, and provides a multimode fusion multiplier, for use in reducing the operation time and power consumption of multipliers. The multiplier is used for implementing a single binary multiplication operation A[m 1-1:0]×B[m 2-1:0], or accumulation and operation of 2N binary multiplications A0[m 3-1:0]×B0[m 4-1:0], wherein m 1≥2N×m 3, m 2≥2N×m 4, and N is a positive integer. The multiplier comprises: P precoders, Q groups of fusion encoders, and a compressor; the P precoders and the Q groups of fusion encoders are all used for encoding a first value and a second value in the single multiplication operation or the multi-multiplication accumulation and operation, and outputting multiple partial products to the compressor, and the compressor can be used for compressing the multiple partial products corresponding to the single multiplication operation or the multi-multiplication accumulation and operation to obtain two accumulated values; during the single multiplication operation, the first value is A[m 1-1:0], and the second value is B[m 2-1:0]; during the multi-multiplication operation, the first value comprises 2N A0[m 3-1:0], and the second value comprises 2N B0[m 4-1:0].
