while i was searching for some counting mechanisms in the P4080, i found a lot of sections in different manuals about performance counters. Several times it lead also to the Event Processing Unit (EPU). Unfortunatelly i couldn't find any more information about that Unit. Also i was not able to find a list of countable events in the P4080 SoC besides the ones directly in the core.
I was wondering, if one can give me a hint where to find further information about EPU and Performance Counter Events.
Thanks a lot for your help and best regards from Germany,
