Hello Peter,
just my two cents regarding eTPU: NXP has more or less left the
PowerPC architecture and favor ARM for automotive applications.
But the MPC5xxx controllers were developed in some sort of cooperation
with ST microelectronics. And ST is still actively playing with this
family. E.g. the SPC564 is still equipped with the eTPU. So the legend
lives on ;-)
indeed, but even ST Micro probably plans to migrate their customers
slowly to their brand new ARM-based chips for automotive: Stellar 32-bit
Automotive MCUs [1]. Although I must add that "Longetivity" is extended
to 20 years for your mentioned SPC56x, whatever that means exactly...
Anyway, I'm afraid, sun is setting on PPC even in automotive business...
I don't really know a lot about the eTPU. But after reading a bit about
it, I stumbled across a presentation from ST and a company called Hycon
(Hybrid Controls) that describes a eTPU to GTM migration (see [1]). The
presentation seems to be part of a Bosch event focused on that GTM (see
[2]). There has been a second event a few years later (see [3]). That
GTM seems to be an IP core that is licensed by multiple chip vendors.
I found it in a number of the PowerPC based chips from ST. But beneath
that, I also found it in some ARM chips from ST that have a "proposal"
status (for example [4]). One of the presentations from Bosch from 2022
mentions that it is implemented by Infineon, ST, Renesas and NXP.
Like I said: I don't really know the eTPU. But if there is a migration
guide, there is a good chance, that it at least works for some cases to
replace the eTPU.
Best regards
Christian
