Is it generally possible to use qa_fft.py or the CGRAN gcellized FFT as offloaded portion, because i want to analyse the benefits of the SPEs on some GNU Radio code. Therefore a benchmark result like this ( http://gnuradio.org/redmine/attachments/104/R-10231-ps3-20090115-0226.png) would be convincing, because you can see the linear dependence between speedup and # of spe's.
