FIR filtter coeff format for BF533

Started by ashr...@rediffmail.com October 31, 2008
hi all
can anyone tell me in what format the fir filter coefficients
should be declared when using with blackfin bf533 processor.
Should the filter coef be in 1.15 format or 1.31 ?
i'm developing an fir decimator and wanted to know format for representation.

thanks
