The universal binary format is a format for executable files that run natively either on both PowerPC-based and x86-based Macs or on both Intel 64-based and ARM64-based Macs. The format originated on NeXTStep as " Multi-Architecture Binaries ", and the concept is more generally known as a fat binary , as seen on Power Macintosh .

The executable formats are registered through the special purpose file system binfmt_misc file-system interface (usually mounted under part of /proc). This is either done directly by sending special sequences to the register procfs file or using a wrapper like Debian-based distributions binfmt-support package [3] or systemd's systemd-binfmt ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.

In computer programming, the Arm Image Format (AIF) is an object file format used primarily for software intended to run on ARM microprocessors. It was introduced by Acorn Computers for use with their Archimedes computer. [citation needed] It can optionally facilitate debugging, including under operating systems running on other processor ...
64-bit Addressing: AArch64 allows the Cortex-R82 to address a much larger memory space compared to its 32-bit predecessors, making it suitable for applications requiring extensive memory. Example : A complex industrial automation system can utilize the expanded address space to manage large data sets and buffers more efficiently, improving ...
