Filter Configuration Options

Single rate, multirate, cascaded, other advanced digital filters

Filter Design HDL Coder™ supports HDL code generation from many types of filters, including those with programmable coefficients, complex input signals, and multiple rates. You can generate HDL code from a filter you designed using a System object™ or adfiltobject.

Featured Examples

HDL Programmable FIR Filter

Illustrates how to generate HDL code for an FIR filter with a processor interface for loading coefficients. The filter can be programmed to any desired response by loading the coefficients into an internal coefficient memory using the processor interface.
