The number of AIE tiles used by a FIR will be given by the formula:
NUMBER_OF_AIE_TILES = TP_CASC_LEN * TP_SSR * TP_SSR * TP_PARA_INTERP_POLY * TP_PARA_DECI_POLY
Examples of this formula are given in the below table.
TP_SSR | TP_PARA_INTERP_POLY | TP_PARA_DECI_POLY | TP_CASC_LEN | Number of tiles |
