ABSTRACT:
A computer system for Fast Fourier Transform provided with a vector functional unit with a process to store rotation factors. The input elements are multiplied in Fast Fourier Transform into an array. When the number of the rotation factors with the same value is not less than the maximum number of vector elements for the vector functional unit, the rotation factor with the same value is stored only once each time the vector elements amounts to the maximum number.
