Well, you will have 5 coefficient multiplies per IIR biquad and 4 or 5
additions which are usually done in parallel or as part of the MAC
instruction (depends on the DSP and fixed point/floating point mode), so
just count the multiplies. The rest is simple arithmetic. Hope this helps.

Hello,
I am trying to choose a DSP for different filtering operations.
I ll use 2 biquad IIR ( 2 IIRs of 2nd order).
I will have 3 input signals that i will sampled at 1khz, 2khz and 10 khz.
How many MIPs odes it cost?
Thank you
