1. What are the typical use cases for utilizing APB over AHB and vice versa?
2. What determines selection of AXI over APB/AHB? Is it just operating frequency or are there some other parameters? At what frequency does we use APB, then AHB and then AXI?
3. Why do we use bridges and not use AXI all over with some modifications like using AXI-Lite where required?
I have gone through their specs but haven't really found satisfactory answers to the above or, I could have missed them. Would really help if someone answers it here!
Thanks, in advance!
