| description | The invention discloses a data read-write method, device and system based on sliding FFT and a storage medium, and relates to the technical field of sliding FFT. The method comprises the following steps which are executed in parallel: after external data are received, writing the external data into a first memory; target external data to be processed in the first memory are read, sliding FFT operation is carried out on the target external data, at least two idle second memories are dynamically called to store operation results in the sliding FFT operation process, and the idle second memories refer to second memories which do not store final operation results of the sliding FFT operation at present; and reading the final operation result of the sliding FFT operation from the second memory which currently stores the final operation result of the sliding FFT operation through the external module. According to the method, the time required by the sliding FFT operation can be reduced.
