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

4 years agoHi,
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
