Abstract
A method for concurrent reading of mixed radix DFT/IDFT data, a method for concurrent calculation of mixed radix DFT/IDFT method, an apparatus for concurrent reading of mixed radix DFT/IDFT data, and an apparatus for concurrent calculation of mixed radix DFT/IDFT. The method for concurrent reading includes: configuring dual circulation parameters according to the number of points corresponding to the number of series to be computed and the number of points corresponding to the number of series accomplished; then, determining the value size between the maximum number of concurrently read data and the product of the number of points corresponding to the number of series accomplished; and based on the result of determination, calculating the dual circulation parameters corresponding thereto according to the result of determination, and concurrently reading data based on the calculated dual circulation parameters.
