As indicated previously, you can specify the coefficient values as non-integer real numbers, with the radix set to 10. For example:
radix = 10;
coefdata = 0.08659436542927, 0.00579513928555, -0.06734424313287, -0.04031582111240;
The coefficients are then quantized by the core to produce the binary coefficient values used in the filter, based on your specified coefficient bit width. This allows you to supply floating-point values derived from a chosen filter design tool and explore the costs and benefits between performance and resource usage by altering the coefficient bit width and observing the alteration in the quantified frequency response in comparison to the ideal response. The basic quantization function is selected by setting the Quantization field to Quantize_Only. See Coefficient Quantization for further details.
The integer values used in the filter implementation can be determined by examining the main core MIF file ( <component_name>.mif ) which is generated in the project directory. The MIF file is always in binary format.
