regarding Symmetric FIR

Hallo ,

       In principle symmetric FIR can run at a speed half that of
Normal FIR but it reqires 3 inputs at a time .

       I am designing a Coprocessor , and my interface is such that i
can only get 2 addresses at a time . What is the solution for me to
get the 3rd address .

            Thanking you all in advance ....

Change the interface. It's not addresses that you need to worry about,
but data paths. It is possible to arrange your memory so that the low
bits of two of the needed addresses are the same, and the coprocessor
drives them in parallel.
