Verilog Code /*-Avago Technologies Confidential -*/ /* Create Date: Design Name: cic_filter Module Name: cic_filter. This project survey review on optimization of CIC filter, and as architecture aspects of up sampling and down sampling rate using CIC filter and comparison between the results in hardware and simulations. CICCompensationDecimator object and set its properties. CIC filter has simple structure, no multiplier, only adder, integrator and register, which can realize high-speed filtering, * * * is often used in the first stage with the highest input the first stage. This paper describes the key points of CIC theory in the Digital Down Conversion (DDC) module of a radar receiver, and takes advantage of the high flexibility and high density feature of Field Programmable Gate Array (FPGA) for putting forth to design the CIC filter by using FPGA. 1 FPGA Technology 58 CIC filters are a class of linear phase FIR filters consisting of a comb part and an integrator part. This paper why it is also well suited for FPGA and ASIC implementation. CIC filters use only adders and registers they require no multipliers to handle large rate changes. (14:49 PM) The previously obscure CIC filter is now vital to many high-volume wireless communications tasks and equipment. Reducing the data rate of such signals would ease the processing significantly.

CIC filter is a common module of wireless communication, which is generally used in digital down conversion (DDC) and digital up conversion (DUC) systems.Key Words : CIC Filter, Compensation Filter, Decimation Filter, Down Converter, Down 16-bit Output Sinc3 Filter Code with three selectable decimation factors 256, 128 and 64 (hardware pin select) 1. 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). Cic filter verilog I want to know whether to use NON-BLOCKING ASSIGNMENT <= or BLOCKING ASSIGNMENT = in Verilog implementation of the constituent integrators and differentiators.
