Hi all,

Sum-Product or Product-Sum, which is better in DSP design?

Thanks!
Davy
 

I think Product SUM as when you do product first, it will need to deal with smaller numebrs requiring lesser memorry and processing power and vice versa.
 

I think it highly depends on the logic functions, e.g., the number of 1's in your Karnaugh Maps.
