Embodiment Construction
[0032] According to an embodiment of the present invention, an FFT / IFFT processor and its processing method are provided, which can be applied to communication systems, communication methods, and processed products in digital multimedia, and are suitable for even-numbered and variable-length transformations in communication systems. FFT / IFFT processing. In the present invention, a four-port storage module, a butterfly arithmetic unit (abbreviated as BF), etc. are introduced, which can realize continuous and uninterrupted processing of data using dual channels under a non-pulsating array structure, reducing the processor's impact on the chip. While meeting the area requirement, a lower clock frequency can be used to complete the required FFT / IFFT operation. The present invention will be described in detail below with reference to the accompanying drawings and examples.
