Design specification
A generalized multiply accumulator is given in the form: P = ∑ X
i
* Y
i
, where X
i
indicates an integer variable or constant, Y
i
indicates an integer variable. Note that a constant-coefficient multiplier is given as a multiplier accumulator with a single term.
Number of product terms:
1
2
3
