Abstract

The invention provides a multiplier, a data processing method and a chip. The multiplier comprises a correction Booth encoding circuit, a correction Wallace tree circuit and a correction accumulationcircuit, the output end of the correction Booth encoding circuit is connected with the input end of the correction Wallace tree circuit, and the output end of the correction Wallace tree circuit is connected with the input end of the correction accumulation circuit. The multiplier can carry out multiplication operation on various data with different bit widths, and the universality of the multiplier is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multiplier, a data processing method and a chip. 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] Generally, existing multipliers using different bit widths can implement multiplication operations for data with different bit widths. However, for low-bit-width data operations, existing multipliers that can handle high-bit-width data cannot be used to perform multiplication operations, resulting in low versatility of the multiplier. Contents of the invention [0004] Based on t...
