For compute, yeah - but Id be extremely surprised if there weren't half a dozen Cortex R or M cores lurking in the uncore. I'd also be surprised if they used custom cores for smaller chips like for airpods/airtags.
- float4 3y ago> I'd also be surprised if they used custom cores for smaller chips like for airpods/airtags. AirTags have an nRF52xxx SoC by Nordic. The only Apple silicon in them is the U1 UWB chip (which is also present in iPhone, HomePod, Watch, ...) which runs on a 16nm Cortex M4. Recent AirPods run on H1 / H2 SoCs though, which are custom Apple chips. Wouldn't be surprised if they are built around the E-cores from the iPhone SoC.
- minimaul 3y agoApple have actually been transitioning to their own tiny core called Chinook (from what I remember it's a tiny ARM64 microcontroller-sized core) running their RTKit.
- my123 3y agoTheir SoCs have quite a number of Cortex-M cores (and Cortex-R for some of them) despite the existence of Chinook.
