FIR filtering in ADSP CM408F


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?

  • 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.
