1. About the CIC Intel® FPGA IP
|Intel® Quartus® Prime Design Suite 19.3
|IP Version 19.3
CIC filters use only adders and registers; they require no multipliers to handle large rate changes. Therefore, CIC is a suitable and economical filter architecture for hardware implementation, and is widely used in sample rate conversion designs such as digital down converters (DDC) and digital up converters (DUC).
