Hi,
If I understood correctly, the composable overlay means you can reconfigure regions on the fly.
No, composable overlays means that you can change the datapath at runtime. Dynamic reconfiguration is part of the composable overlay but not strictly necessary.
Say within one frame I need to execute more functions than the number of available regions, will the composable overlay reconfigure one region dynamically to finish working on that frame? ie including the reconfiguration process in the list of tasks to be executed?
You can reconfigure the the region dynamically, if the composable overlay has DFX regions. Depending on the size and configuration of the hardware you may be able to reconfigure the hardware while data is on flight. However, for video streams this is not possible. Typically, you will have everything configure before feeding the video to the composable overlay.
Have a look at this video. It may help clarifying your questions
