Benchmarking Frame-Based Models Using Feedback in Simulink

 Learn how to benchmark different implementations of a frame-based 8th-order elliptic low-pass filter. Observe how small details in the implementation can greatly impact simulation speed. 

Start by benchmarking the speed of a sample-based implementation of said filter to serve as a common reference point. Then, change one thing in the model at a time and observe the impact on simulation speed. In the process of benchmarking, you’ll compare:  

1. Frame-based vs. sample-based implementations  

2. Monolithic-based vs. primitives-based IIR filter implementations  

3. Normal mode vs. accelerator run modes  

4. For-Iterator–based vs. standard IIR implementations  

5. Different buffering approaches
