Overview
The CIC Intel FPGA IP core implements a Cascaded integrator-comb (CIC) filter with data ports that are compatible with the Avalon® streaming (Avalon-ST) interface. CIC filters (also known as Hogenauer filters) are computationally efficient for extracting baseband signals from narrow-band sources using decimation. They also construct narrow-band signals from processed baseband signals using interpolation.
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).
Key features
- Interpolation and decimation filters with variable rate change factors (2 to 32,000), a configurable number of stages (1 to 12), and two differential delay options (1 or 2).
- Single clock domain with selectable number of interfaces and a maximum of 1,024 channels.
- Selectable data storage options with an option to use pipelined integrators.
- Configurable input data width (1 to 32 bits) and output data width (1 to full resolution data width).
- Selectable output rounding modes (truncation, convergent rounding, rounding up, or saturation) and Hogenauer pruning support.
- Optimization for speed by specifying the number of pipeline stages used by each integrator.
- Compensation filter coefficients generation.
