FIR filtering in ADSP CM408F

Hello,

I wanted to know if the analog devices processor ADSP-CM408F is capable of doing FIR and IIR filterinig and does it have enough processing power to do it?

If yes how can you prove it? if not why not?

Thanks

  • Sure, it can. You can write your own FIR filter (for example you can write a simple C loop to multiply filter coefficients by tap signals every time you get a new input sample). A much more efficient way is using CMSIS DSP library (search for arm_fir_f32 or arm_fir_fast_q15).

    Of course, the processing power you need depends on the input sampling frequency, number of filter taps, etc.
