<DIV><FONT face=Arial size=2><SPAN class=546071915-22102009>The QDMA portion
appears to work fine. I verified this by
loading increasing integers (cast as floats) into the RAM
starting at address 0x80000000, QDMAing the data to the internal memory and
then QDMAing it out starting at 0x803A9800 without doing any FFT
functions. I exported this file and analyzed it in matlab, and it was
perfectly intact. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=546071915-22102009>Performing the STFT
on the data produces QNANs and INFs in the data output, however,
a single FFT works fine. I can QDMA any chunk of 8192 complex
samples, take the FFT, QDMA it out to 0x803A9800, export it to matlab and
it looks fine. It seems multiple FFTs cause issues... I will continue
to work at it, but any input you might have would be greatly
appreciated.</SPAN></FONT></DIV>
