What instructions set architecture does the NVIDIA Jetson AGX Xavier series run? e.g. x86, x86-64, ia64, ppc64, sparc-32, sparc-64, etc. or is it proprietary.
Jetson Xavier like all members of the Jetson family have ARM CPU cores. With respect to the CPU component, the instruction set is some variant of the ARM instruction set (varies depending on Jetson family member). With respect to the GPU component, the instruction set it is some variant of CUDA SASS.
Mostly you can refer to any of these for the 64-bit systems (you’d have to go all the way back to the TK1 to see 32-bit):
