Hi

What is optimal way of adding 8 x8 matrix elements?

Can you suggest time based and area based approaches?
 

Optimal is whatever it happens to be depending on your constraints. At one end of the spectrum: you have only one adder, and you do 64 consecutive add operations. Other end of the spectrum, 64 adders that add all the matrix elements simultaneously. And all sorts of trade offs in between, the choice of which depends roundabout 100% on your design requirements.
