Microprocessor with circuit for series calculation
A microprocessor having the capability of executing a micro-instruction for series calculation is provided. The microprocessor includes an instruction decoder and an execution circuit for series calculation. The micro-instruction whose source operands correspond to an undetermined number x and a plurality of coefficients a0 to an (for x0 to xn) is decoded by the instruction decoder. Based on x and a0 to an, the execution circuit for series calculation includes at least one multiplier for calculating exponentiation values of x (e.g. xp), and includes at least one MAU (multiply-and-accumulate unit) for combining x, the exponentiation values of x, and the coefficients a0 to an for the series calculation.
