Data processing apparatus, data processing method, and computer product

A data processing method that is executed by a computer, the data processing method comprising:

• performing a matrix computation between data streams whose unit data is of a matrix format;
• determining for each matrix obtained by the matrix computation by the computing unit and based on the value of each element included in the matrix, an exponent value for expressing each element included in the matrix as a floating decimal point value;
• converting the value of each element into a significand value of the element, according to the exponent value determined at the determining;
• and
• correlating and outputting the exponent value and each matrix after conversion in which the value of each element in the matrix has been converted at the converting.

A non-transitory, computer-readable recording medium that stores a data processing program that causes a computer to execute a process comprising:

• performing a matrix computation between data streams whose unit data is of a matrix format;
• determining for each matrix obtained by the matrix computation by the computing unit and based on the value of each element included in the matrix, an exponent value for expressing each element included in the matrix as a floating decimal point value;
• converting the value of each element into a significand value of the element, according to the exponent value determined at the determining;
• and
• correlating and outputting the exponent value and each matrix after conversion in which the value of each element in the matrix has been converted at the converting.
