If the sampling rate and clock frequency are the same, basically as many multipliers as the number of taps are needed.
If the sampling rate is lower, the difference must be more than an integer ratio, but the process of time division multiplexing is performed, i.e., the number of multipliers can be saved to a number corresponding to a ratio less than half.
In BSP Builder, the RTL is first generated in Simulink Simulation, so the number of estimates The final result is compiled in Quartus® Prime.
