Hello everyone!
I searched through the docs of the Cortex A9, but I can't find anywhere this information. I saw that for the cortex A53 the ACP slave is capable of handling 4 outstanding requests (read + write combined), but for the cortex A9 ths information is not specified. I have a PYNQ board (cortex A9) and I did some experimentation and it seems that the AXI3 slave in the SCU is capable of handling only 1 outstanding read request, but I am not sure since this may also be an issue with the HLS code that I have written.
Please, if anyone has any idea regarding the number of outstanding requests that the ACP slave is capable of handling, I would really appreciate it!
Cheers,
