13.1.1. DSP Builder FIR and CIC Filters

Finite impulse response (FIR) and cascaded integrator comb (CIC) filters share many common features and use advanced high-level synthesis techniques to generate filters with higher clock speeds, lower logic, multiplier, and memory counts. Using these high clock rates allows you to reduce your costs by choosing smaller FPGAs.
