Pretty much a GPU alike stuff with arm-8 set to be able to run its OS.

- floatboth 6y agoNo, it's not a proprietary extension, it's Arm's Scalable Vector Extension!
- d_tr 6y agoI do not get the "not exactly ARM" bit. The chip has a lot of cores that execute standard ARM code with SVE instructions mixed in. You can download the manual for the SVE from ARM's website. Following a quick search I also see that GCC has a flag for generating SVE instructions.
