Multiplier for floating-point operation, method, integrated circuit chip, and calculation device

(canceled)

A method configured to execute a multiplication computation of floating-point numbers through using a multiplier, wherein the floating-point numbers at least include an exponent and a mantissa, and the multiplier executes a multiplication computation based on a computation mode, and the method includes:

• using an exponent processing unit of the multiplier to obtain an exponent after the multiplication computation according to the computation mode, an exponent of a first floating-point number and an exponent of a second floating-point number;
• using a mantissa processing unit of the multiplier to obtain a mantissa after the multiplication computation according to the computation mode, a mantissa of the first floating-point number and a mantissa of the second floating-point number,
• wherein the computation mode is configured to indicate a data format of the first floating-point number and a data format of the second floating-point number.
