14. PARALLEL_ADD (Parallel Adder) IP Core

The PARALLEL_ADD IP core performs add or subtract operations on a selected number of inputs to produce a single sum result. You can add or subtract more than two operands and automatically shift the input operands upon entering the function. The method of shifting input operands is useful for serial FIR filter structures requiring a shift-and-accumulate of the partial products.

The following figure shows the ports for the PARALLEL_ADD IP core.
