I am working on DSK5416 and CCS.
I'm doing real-time using DMA and McBSP to communicate with the codec. I'm
working with 16 bits words and with DSP/BIOS configuration.
I would like to know if the problem that I have is coming from data
After interruption (full buffer: 1024 words of 16 bits) I use the following
// Input FFT
// Matched Filter
for (i=0; i
I also have the following extra configuration file:
InBufferSect: > IDATA PAGE 1,align(0x800)
OutBufferSect: > IDATA PAGE 1,align(0x800)
FAsyncBufferSect: > IDATA PAGE 1,align(0x800)
As you can see after interruption I’m doing an fft of the receive buffer
and a matched filtering.
My problem is when I’m computing the ifft of vector FiltreAdaptesync the
result of the fft OutBuffer is not good. However, when I don’t compute the
ifft, then the result of OutBuffer fft is good. I don’t understand why.
Thank you for your help
