Claim 24:
25. An apparatus for processing discrete Fourier transform (“DFT”) for data transmission comprising:
means for receiving a data stream containing a plurality of DFT jobs wherein a first portion of DFT jobs has a first DFT point size and a second portion of DFT jobs has a second DFT point size;
means for generating a first mega-job configured to bundle at least a portion of the DFT jobs with the first DFT point size in a predefined sequence;
means for storing the first mega-job at a ping half-side of a ping-pong memory bank before allowing the first mega-job to be fed to a vector pipeline for radix computation; and
means for determining a radix factorization for calculating DFT in response to the first DFT point size.
