Title:
METHOD AND APPARATUS FOR FLOATING POINT ARITHMETIC
Document Type and Number:
WIPO Patent Application WO/2023/113445
Kind Code:
A1
Abstract:
The present invention relates to a floating point arithmetic technology, and is characterized by: on the basis of the result of comparing exponent parts of at least two operands being input, storing bit information of a mantissa part of any one operand from among the at least two operands; outputting an operation result of higher bits by calculating the at least two operands; and outputting an operation result of lower bits by adding, to the bit information of the mantissa part, a bit being lost through a normalization operation and a rounding operation during the calculation of the at least two operands. Accordingly, the present invention can accelerate high-precision arithmetic by adding, to a floating point operator, hardware that calculates an error in a floating point addition operation, and, via instructions supporting same, can configure an efficient processor.
