Embodiments disclosed in this application pertain to the field of computer technologies, and in particular, to a method for performing FFT, a processor, and a computing device. The method includes: A processor responds to an execution request of fast Fourier transform FFT calculation of an application, and decomposes the FFT calculation into a plurality of calculation stages. The processor sequentially executes the plurality of calculation stages, where when a target calculation stage is executed, a vector operation circuit performs rotation factor calculation, and a matrix operation circuit performs DFT calculation. After the execution of the plurality of calculation stages is completed, the processor determines an execution result of the FFT calculation based on an execution result of a last calculation stage, and returns the execution result to the application. vector operation circuit matrix operation circuit
