2.6.3. Adder Trees

Structuring adder trees appropriately to match your targeted Intel FPGA device architecture can provide significant improvements in your design's efficiency and performance.

A good example of an application using a large adder tree is a finite impulse response (FIR) correlator. Using a pipelined binary or ternary adder tree appropriately can greatly improve the quality of your results.

This section explains why coding recommendations are different for Intel 4‑input LUT devices and 6‑input LUT devices.
