When developing software for embedded systems, you may need to support multiple architectures such as arm, mips, x86, powerpc, alpha etc.. but you may not have the hardware required on hand to test them. This is where QEMU – a processor emulator – comes to the rescue. In a way, QEM...
Thanks to the diligent work of the project developers (and often the code's relatively straightforward portability), the emulators for fourth-gen consoles have been successfully adapted for ARM and are ready for use on Apple Silicon. As you'd expect, the low computational requirements for fourth ...
The RaspberryPi is an ARM computer and most Macs (until a few months ago) are X86. That means I need an emulator, not just an OS conatiner wrapper like Docker. Fortunately the open source emulation tool QEMU is up to the task. Followingthe instructions here, I was able to download and...
There are two common ways of running a virtual machine. The Mac can use a technology called Hypervisor, which makesrunning other virtualized versions of macOS or Windows on ARM very easy. This led to some confusion, because UTM on the Mac is allowed to use Hypervisor, but Apple doesn’t e...
Emulating x86-64 system hardware and processor on an Apple silicon Arm AArch64 system hardware and processor, sufficient to boot an operating system? From Apple? Absolutely not going to happen. Rosetta 2 does user-mode x86-64 emulation, uses calls macOS itself to run the macOS code, and is...
micro-architecture in software with many of the modern CPU techniques like pipelining, out of order execution, store buffering, speculative execution, register renaming. The actual instruction set for the time being is a fake one, but perhaps in the future I'll pick ARM or X86 or something ...
But the issue I have run into, and will keep running into is asking one of my mates to pass me their ARM MacBook to give me their aarch64 compiled versions of their apps. My tool has the 2 paths: x86_64, or aarch64. The rest can go and get blocked, with a message saying it...

Since the x86 emulation is written in portable C++ code, it could be one solution to running x86 Windows applications on ARM devices, like Android tablets. Wine is already available on ARM Android, but it can only run Windows software compiled for ARM — there's no emulation layer. Here's...
