ippStsIIRGenOrderErr
IIR design routines build recursive filter coefficients from a requested order and frequency constraints. If the order is outside the supported range, IPP cannot create a stable filter description.
This should be treated as a configuration error in the filter-design path rather than an arithmetic failure during filtering.
Check these details
- The exact IIR family requested by the caller.
- The documented order limit for that family.
- Whether a UI filter-length field is accidentally passed as IIR order.
