How to update PEQ parameters from MCU?

I need to update gain, Q and frequency from MCU to PEQ. For gain I have a lookup table with 50 values, Q lookup table has 16 values and frequency lookup table has 50 values.


I guess I could use the filter coefficient calculator in SigmaStudio to calculate coefficients for every each option but that is lot of data to store into MCU (I have to do same thing for some LPF and HPF filters also). Is there a better way to do it? Like using lookup tables in DSP side?
