The Playstation 4 does this as the south bridge is really just an ARM chip. So I think you are right.

- monocasa 10y agoAnd the PS3 before it. And the WiiU, and the Wii. And every AMD chip since about 2013 (AMD Platform Security Processor, their equivalent of Intel's ME). Honestly, pretty much every complex electronic device (and quite a few not so!) out there has a bunch of ARMs inside of it doing system management. This is borderline a non-story IMO. Hell, an ARM7TDMI was a pretty common core to use on SD cards a few years back. The damn things are everywhere.

- wmf 10y agoThe PS4 southbridge has 256MB of RAM, runs FreeBSD, and downloads game patches and such. This seems far more ambitious than a BMC/ME.
- throwawayish 10y agoNot really, the ARM in the SB is much more like a ILOM system; not much different from the various processors scattered around hardware these days, be it ARM or some other more niche architecture, or even special-purpose archs.
