Abstract

The invention provides a multiplier, a data processing method, a chip and electronic equipment. The multiplier comprises a regular signed number encoding circuit, a compression tree group circuit andan accumulation circuit, the output end of the regular signed number encoding circuit is connected with the input end of the compression tree group circuit; the output end of the compression tree group circuit is connected with the input end of the accumulation circuit; the multiplier can compress a partial product of a target code through the compression tree group circuit to obtain a target operation result, and can perform regular symbolic number coding on received to-be-processed data to reduce the number of effective partial products in multiplication so as to reduce the complexity of multiplication.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multiplier, a data processing method, a chip and electronic equipment. Background technique [0002] With the continuous development of digital electronic technology, the rapid development of various artificial intelligence (AI) chips has higher and higher requirements for high-performance digital multipliers. The neural network algorithm is one of the algorithms widely used in smart chips, and the multiplication operation through the multiplier is a common operation in the neural network algorithm. [0003] At present, the multiplier uses every three-digit value in the multiplier as a code, and obtains partial products according to the multiplicand, and uses Wallace tree to compress all partial products to obtain the result of multiplication. However, in the conventional technology, the number of non-zero bit values ​​in the code is large, and the number of corres...
