Fully Parallel Systolic FIR Filter Implementation
This example shows how to implement a fully parallel 25-tap lowpass FIR filter by using the Discrete FIR Filter block.
The model filters new data samples at every cycle.
Open the model. Inspect the block parameters. Filter structure is set to
Direct form systolic.
Run Model and Inspect Results
Run the model. Observe the input and output signals in the generated plots.
Use the model toolbar to open the Logic Analyzer. If the button is not displayed, expand the Review Results app gallery.

Generate HDL Code
To generate HDL code from the Discrete FIR Filter block, right-click the block and select Create Subsystem from Selection. Then right-click the subsystem and select HDL Code > Generate HDL Code for Subsystem.
