Electronic device including neural processing unit supporting different data types and method for controlling the same

A method of electronic device, comprising:

• combining, in response to receiving a request for performing multiplication based on a plurality of integer numbers of a second data type for indicating integers that is different from a first data type for indicating floating-point numbers, a first integer number and a second integer number among the plurality of integer numbers;
• transmitting, to a first port of a multiplier for obtaining a product of bits corresponding to mantissas of the floating-point numbers distinguished by the first data type, a third integer number of the plurality of integer numbers based on number of bits of the mantissas;
• transmitting, in a state that the third integer number is transmitted to the first port, a fourth integer number indicating a combination of the first integer number and the second integer number to a second port of the multiplier different from the first port;
• and
• obtaining, in response to identifying a fifth integer number indicating a multiplication of the third integer number and the fourth integer number from a third port of the multiplier that is different from the first port and the second port of the multiplier, a sixth integer number indicating a multiplication of the first integer number and the third integer number, and a seventh integer number indicating a multiplication of the second integer number and the third integer number, based on the identified fifth integer number.

An electronic device, comprising:

• a first combiner circuitry to combine, in response to receiving a request for performing multiplication based on a plurality of integer numbers of a second data type for indicating integers that is different from a first data type for indicating floating-point numbers, a first integer number and a second integer number among the plurality of integer numbers;
• a second combiner circuitry to combine, in response to receiving the request, a third integer number and a fourth integer number among the plurality of integer numbers;
• a multiplier circuitry to obtain multiplication of bits corresponding to mantissas of the floating-point numbers distinguished by the first data type, wherein a fifth integer number indicating combination of the first integer number and the second integer number by the first combiner circuitry is inputted to a first port of the multiplier, and a sixth integer number indicating a combination of the third integer number and the fourth integer number by the second combiner circuitry;
• a conversion circuitry to obtain, in response to identifying a seventh integer number indicating multiplication of the fifth integer number and the sixth integer number from a third port different from the first port and the second port of the multiplier, based on the seventh integer number, multiplication of one of the first integer number or the second integer number, and one of the third integer number or the fourth integer number.
