Product Description

The Cascaded Integrator Comb (CIC) Filter, or Hogenauerfilter, is a multiplier less filter architecture that is extremely important for implementing area efficient high sample rate changes in Digital Down Converters (DDC) and Digital Up Converters (DUC). Although its algorithm is quite easily understood, hardware engineers are looking to avoid the time consumed by implementing and maintaining their own IP, while also looking to be able to make quick, informed and resource efficient implementation decisions.

The CIC Compiler reduces filter implementation time to the push of a button, while also providing users with the ability to make trade-offs between differing hardware implementations of their CIC Filter specification. These easily made trade-offs give users the ability to select the most resource and power efficient solutions for their specific applications.
