What is the number of minimum DSP required to achieve D(32 bit)=A(5 bit)*B(32 bit)+C(32 bit) functio

What is the number of minimum DSP required to achieve D(32 bits)=(A(5 bits)*B(32 bits)) truncated to 32 bits +C(32 bits) function, and the modes of the DSPs

Hi,


Which device you are targeting and generally DSP slices has 25x18 multipliers but you have the input of 32 bits.

In general 1 multiply and addition operation consumes 1 DSP slice.



Above figure will use 2 DSP slices, considering x[n] and c[n] is of 15-bits.


Thank you
