Description

Technical field [0001] The present application relates to the field of computer technology, and in particular, to a multiplier, data processing method, and a chip. Background technique [0002] With the continuous development of digital electronic technology, the rapid development of all kinds of artificial intelligencers (AI) chips is also higher and higher in high performance digital multipliers. As one of the algorithms widely used by the intelligent chip, the neural network algorithm is used by multipliers to multiply in a neural network algorithm. [0003] Typically, multiplication operations of different bit wide data can be implemented in different bit wide existing multipliers. However, for low-wide data operations, multiplication can be used to process existing multipliers that can handle high wide data, resulting in a low versatility of the multiplier. Inventive content [0004] Based on this, it is necessary to provide a multiplier, data processing method, and chip ca...
