CIC comb-shaped filter is widely used in high-speed extraction or interpolation system due to its characteristics of simple structure,small memory,no multiplier,high speed,etc. A simulation model of four-order CIC comb-shaped filter was established in Simulink platform by means of DSP Builder software. Through a variety of EDA tools’simulation and analysis,a high-speed CIC comb-shaped filter with highest response velocity of 138.89 MHz was achieved on EP2C35F484C8 FPGAs. Its performance is far better than that of the DSP general-purpose processor. This new design concept has important reference value.
