Is FINN able to process multiple inputs as a pipeline ?

[kalahel]

Hello,

Is it possible for FINN to handle multiple input images before one inference has ended, in a full stream manner ?

For example :

-> Sending image 1 on input DMA
Running inference of image 1
-> Sending image 2 on input DMA
Still running inference of image 1
-> Sending image 3 on input DMA
Still running & finishing inference of image 1
<- Retrieving inference 1 on output DMA
Running & finishing inference of image 2
<- Retrieving inference 2 on output DMA
Running & finishing inference of image 3
<- Retrieving inference 3 on output DMA

Because from all the tests I did, the Input DMA never returned an idle signal before the entire inference was over.

I was in fact polling the wrong registers.
FINN does not uses Vivado DMA IP described here.
It uses AXI4-Lite control interface.
