    摘要： A processor includes: an exponent generating unit (20) that generates an exponent part of a coefficient represented by a floating point number format based on a first part of received input data, the coefficient being obtained when an exponential function is decomposed into a series operation and the coefficient for the series operation; a storage unit (21) that stores a mantissa part of the coefficient; a constant generating unit (20) that reads constant data corresponding to a second part of the input data from the storage unit; and a selecting unit (23) that selects and outputs the constant data from the constant generating unit when an instruction to be executed is a coefficient calculation instruction for calculation of the coefficient of the exponential function.
