HDL Code Generation For Digital Filters   10:19

Apply Model-Based Design to design a fixed-point digital filter and generate HDL code for implementation on FPGA or ASIC hardware.

HDL Butterworth Filter  

This example illustrates how to generate HDL code for a 5th order Butterworth filter. The cutoff-frequency for this filter is very low relative to the sample rate, leading to a filter that is difficult to make practical.

HDL Inverse Sinc Filter  

This example illustrates how to generate HDL code for an inverse sinc (sin x/x) peaking filter that adds preemphasis to compensate for the inherent sinc response of the digital-to-analog converter (DAC).

HDL Minimum Phase FIRT Filter  

This example illustrates how to generate HDL code for a minimum phase FIRT filter with 10-bit input data and 10-bit output data.

HDL Tone Control Filter Bank  

This example illustrates how to generate HDL code for bank of 24 first-order shelving filters that implement an audio tone control with 1 dB steps from -6 dB to +6 dB for bass and treble.

HDL Video Filter  

This example illustrates how to generate HDL code for an ITU-R BT.601 luma filter with 8-bit input data and 10-bit output data.

HDL Serial Architectures for FIR Filters  

This example illustrates how to generate HDL code for a symmetrical FIR filter with fully parallel, fully serial, partly serial and cascade-serial architectures for a lowpass filter for an audio filtering application.

HDL Programmable FIR Filter  

This example illustrates how to generate HDL code for an FIR filter with a processor interface for loading coefficients.

HDL Distributed Arithmetic for FIR Filters  

In this example, we show how you can generate HDL code for a lowpass FIR filter with Distributed Arithmetic (DA) architecture.

HDL Digital-Up Converter  

This example illustrates how to generate HDL code for a Digital-Up Converter (DUC). A DUC is a digital circuit which converts a digital baseband signal to a passband signal.

HDL Sample Rate Conversion Using Farrow Filters  

In this example, we show how you can design and implement hardware efficient Sample Rate Converters for an arbitrary factor using polynomial-based (Farrow) structures.

HDL Filter Link  

This example shows how to use FDATool to design a filter, generate a structural model of the filter in Simulink^® , and generate HDL. It also shows how to use an HDL simulator to cosimulate the Simulink behavioral model and the generated HDL.
