Additionally, unlike Intel or AMD CPUs, there is no ARM processor manufacturer. Instead, the processing unit is on the same physical substrate as the other hardware controllers this is an integrated circuit. Components can be changed or expanded without affecting connectivity or the overall hardware platform.ĪRM processors do not have a separate CPU. Most components have separate chips called controllers. In an architectural sense, the hardware components within an x86 system–like sound and graphics cards, memory, storage, and the CPU–are all independent of each other. X86 processors are familiar to many in IT because this is the type of processor used in most computer and server hardware. Lastly I'd likely as a follow-up question on the Raspberry Pi Stackexchange site.To set some context, let’s briefly define x86 and ARM processors. So my expectation would be that you'd be able to use the same binaries on both. In terms of your question about running Archlinuxarm built specifically for the 410c on a Raspberry Pi 3, my suggestion would be to try it.īoth of those CPUs are ARM processors as shown here: I'll try and answer the most important though.įor the specifics on this, you'd have to ask the Arch community why they opt to do things within that project. You're asking questions that are too numerous to answer in a single question. So aarch64 and arm64 refer to the same thing. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.Īs far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64. Therefore the GNU triplet for the 64-bit ISA is aarch64. The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. With these 2 architectures I was able to find this answer from SO: titled: Differences between arm64 and aarch64, which stated the difference as follows:ĪArch64 is the 64-bit state introduced in the Armv8-A architecture. NOTE: You'll also hear machine code referred to as assembly language. Incidentally instructions in an instruction set typically look like this: x86 nasm - extern printf This machine code is the instructions from a CPU's instruction set. The interface to the instruction sets is what compilers convert higher level programming languages, such as C/C++, down to machine code. Instruction setsĪt the heart of every microprocessor is a set of instructions that it can perform. I typically reference this Wikipedia page titled: List of instruction sets, since it's the most complete list I've ever seen on the Internet. aarch64.Īt the heart of your question is that different CPUs provide different instruction sets. The fundamental difference between the different implementations of arm64 vs. Your question could be interpreted as pretty broad, but I think what you're actually asking about is extremely specific. instead of different vendors' different products? Is it means that for example instruction set in DragonBoard 410c is different from Raspberry Pi 3? Or in other word, If I install Archlinuxarm for DragonBoard 410c to Raspberry Pi 3, What will happen? Can it boot properly? What makes me confused is the reason why archlinuxarm community doesn't provide stage rootfs tarball for only arm64 armel and etc. Are there distribution for different platform just different in their driver or the difference of parameters when compiling Linux kernels? Is it just can't be maximum optimized or completely not compatible? If I install a archlinuxarm system for A platform to B platform. However, for armv8, there is a download option of archlinuxarm which is Generic. Maybe, it is because the difference of Endian. Unfortunately, it is said that shell interpreter is not executable(in different architecture). Then I open Termux and typed: proot -r /path/to/my/archlinuxarm/rootfolder/ tar.gz file to a folder in Termux home directory. I download Archlinuxarm for armv7 - Raspberry Pi 2. My mobile phone's architecture is arm64v7el (4*ARMCortex-A73+4*ARMCortex-A53). In order to figure out Q1, I use my mobile phone to try those. What is the difference of those support platform of Archlinuxarm? Here is the list of arm support platforms of Arch Linux ARM.īut for Debian, there is no such many choice(only arm64 and for little endian there is only armel). For Linux distributions for arm64/arch64 there is a lot of orientation. However, as for arm64/aarch64(the difference of arm64/aarch64 is here), there are a lot of vendors. The software for this architecture can run on it properly. For x86_64 architecture CPU, no matter it is made by Intel, AMD or VIA.
