altmult_add

Thank you for your reply.

1. It is already pipelined.

2. Im not quite sure what you mean? do you mean 2 vectors with 3 elemenents in each:

sum(

a(0) * b(0)

a(1) * b(1)

a(2) * b(2)

);

?

In this case you need 3 multipliers and 2 adders.

i did mistake and yes you are right that i need 3 multipliers.

I would suggest the altmult_add will probably work better than a custom made pipeline, if it suits your purpose.out?

Thank you for suggestion.

Why not simulate them and find

--- Quote End ---

I'm a beginner. Sometimes my simulation results may be different real works on DE2-115 board. Nevertheless i have trying to simulate.

Well, i have implemented my calculations in pipelined structures and i think that this type implementations need latencies of the pipelined blocks. i have searched to find whether altmult_add megafunction has a latency or output ready signal?

if i have to calculate the equation below how can i detect that the output of the altmult_add is ready for adder which will add the output of the altmult_add to 5?

sum(

a(0) * b(0)

a(1) * b(1)

a(2) * b(2)

) + 5;
