Hi Tsvetolin,

Thanks a lot for the information you provided which is very helpful.

I need a phase lead compensator in the processor for real time audio signal processing.

Could I write my transfer function to the processor?

How can I implement it?

Best, Hai

Hai,

It is possible to make various audio processing with c55x DSPs. Unfortunately I can not suggest you a complete decision about phase lead compensation but you can find some examples about audio processing in CSL v3.08 packet at:

Hi Tsvetolin,

How many microphones could be connected to one TMS320C5517?

I have 13 microphones and each one would have its own digital filter in DSP.

Thanks a lot.

TMS320C5517 has 3 I2S lines which limits the maximum connected microphones to 6 as using microphone array boards. You can find more details at:
