Abstract

The invention provides a data selector, a data processing method, a chip and electronic equipment. The data selector comprises a data read-in circuit, a cyclic comparison circuit, an end judgment circuit and an extreme value register circuit, the output end of the data read-in circuit is connected with the first input end of the cyclic comparison circuit; the first output end of the cyclic comparison circuit is connected with the first input end of the extreme value register circuit and the input end of the end judgment circuit; the output end of the ending judgment circuit is connected with the second input end of the extreme value register circuit, the first output end of the extreme value register circuit is connected with the second input end of the cyclic comparison circuit, and the data selector can perform cyclic comparison on N pieces of data to obtain a maximum value and a minimum value in the N pieces of data; in addition, the data selector can process a plurality of data comparison operations with different bit widths according to different function selection mode signals received by the cyclic comparison circuit, so that the area of an AI chip occupied by the data selector is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data selector, 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 comparators. The neural network algorithm is one of the algorithms widely used in smart chips, and the operation of selecting extreme values ​​from multiple data is a common operation in the neural network algorithm. [0003] Usually, because a large amount of various data needs to be input to the data comparator for comparison, and the existing data comparator can only compare two data at a time, resulting in an excessive amount of computation of the data comparator and a long computation time , affecting the processing efficiency of the data comparator. In addition, when mult...
