Rosetta 2
A binary translation layer technology introduced by Apple that translates Intel (x86_64) instructions into Apple Silicon (ARM) instructions at runtime, enabling older Intel applications to run on the new architecture Mac using a two-phase AOT and JIT translation mechanism.
Core Facts
Timeline (last 90 days)
Apple's Rosetta 2, Microsoft's Prism, and the open-source FEX-Emu and Box64 are all x86-to-ARM binary translation solutions.
FEX-Emu uses a JIT approach, while Rosetta 2 has both AOT and JIT modes, triggering AOT translation and caching on the first run of an application.
Rosetta 2 is a translation layer technology that can translate Intel (x86_64) instructions into Apple Silicon (ARM) instructions at runtime.
The technical implementation of Rosetta 2 consists of two phases: ahead-of-time (AOT) translation and just-in-time (JIT) translation.
Under Apple Silicon's unified memory architecture, native Swift applications can run directly on the ARM instruction set without requiring the Rosetta 2 translation layer.
Apple's M-series chips switched from x86 to ARM architecture, requiring the Rosetta 2 translation layer to run legacy x86 Mac applications.
