Abstract
Methods and apparatus for job scheduling in a programmable mixed-radix DFT/IDFT processor. In an exemplary embodiment, a method includes receiving a plurality of discrete Fourier transform (DFT) jobs. Each job identifies a computation of a DFT of a particular point size. The method also includes bundling selected jobs having a selected point size into a mega-job, and identifying a radix factorization for the selected point size. The radix factorization includes one or more stages and each stage identifies a radix computation to be performed. The method also includes computing, for each stage, the identified radix computations for the selected jobs in the mega-job. The radix computations for each stage are performed for the selected jobs before performing radix computations for a subsequent stage. The method also includes outputting DFT results for the selected jobs in the mega-job.
