I'm curious if someone could explain the architectural differences between ppc64le and aarch64? I've always heard they are quite similar.

- tyingq 6y agoSince you mentioned ppc64le, there's also aarch64eb (arm64 in big endian mode). I saw that NetBSD supports it. It seems like support for other operating systems is limited mostly because of issues around booting...not the actual kernel or userland itself.
- arnd 6y agoMIPSr6, aarch64 and riscv are siblings born from MIPSr5 plus the best of other RISC architectures. ppc64le and 32-bit Arm are part of the wider family, but have some notable differences that make them slightly less RISC-like. Both include e.g. more complex condition code handling and instructions that operate on more than three registers.
