10. ALTMULT_ACCUM (Multiply-Accumulate) IP Core
The ALTMULT_ACCUM IP core allows you to implement a multiplier-adder.
The following figure shows the ports for the ALTMULT_ACCUM IP core.
A multiplier-accumulator accepts a pair of inputs, multiplies the two inputs together, and feeds their result into an accumulator to be added to or subtracted from its previous registered result. This function is expressed in the following equation.
Where N is the number of cycles of data that has been entered into the accumulator.
