Max number of FIR filter coefficients

hi, my question is quite general for FPGA devices. i have a matlab code for a BP FIR filter with a very large number of coefficients, from 2k to 20k and above. if i would implement the filter ...

hi,

tnx for the comments, i'll read the notes.

the filter supossed to be a very narrow high prefomence band pass (based on a paper), that's why it has this huge amount of coefficients (as dave said).

it is a type I fir so it is symmmetrical with and odd length.

the writers of the paper implement the filter with a TI 8 or 32 core DSP, and we wondered if its possible in a FPGA as is.
