Those are interesting patents.

The first few claim memory runs at different voltages (higher and lower) than logic circuits. That revelation came to Apple in 2008. Seems kind of late to me. Didn't we have that capability back in the early days of 80186 and 80286? How about those 68000 boxes, wouldn't they have had memory running at different voltages than their CPU's? Apple may be making this claim for cache memory, I guess. Got to figure that was a pretty common occurrence within the Bios of the Y2K era. Oh those were all manual tweaks though.

The second bunch have to do with voltage areas. That might be a new thing and Qualcomm might even practice something like that. I wonder if they too have any patents down this line of power management. One has to suspect this to also be a common area of practice within many ARM and x86 chipsets, especially SOC's. Oh well, this one looks like it dictates further research. I wonder where Apple got all the details about "CPUQACTIVE" and such. It looks like someone gave them some manuals or ???? Maybe, this bunch is all just standard ARMv8 protocol.

The last bunch just seem to replace "area" with "domain". The claims within these patents also adds a setting of state which I guess differentiates them from the above group. Lots of ARMv8 noise in this discussion too.

I'll just leave it at this for now. The complexity of it all is obviously in the details. Common folk aren't going to there though.
