Now with the AOT compiler on Rosetta 2, Apple Silicon is able to translate and compile the code on the fly through dynamic binary translation. Earlier with Rosetta in 2006, Apple was only using the Just-in-time (JIT) compiler for static binary translation. Now the question comes, how does this translation happen and how is Rosetta managing to run heavy x86 apps on ARM Macs seamlessly? You can attribute the main reason to the Ahead-of-time (AOT) compiler that Apple has deployed on Rosetta 2. Since x86 and ARM architectures are drastically different, this translation is required for smooth functioning of Intel-based apps. When I say instruction set, it means the commands (also called machine code in computing) needed to execute a program of one architecture on another.

But how does this powerful translation layer work? There is little information on this subject so we will try to dissect Rosetta 2 and understand how Rosetta 2 functions.ДЇirst of all, Rosetta 2 is a translation layer which means it translates the instruction sets of Intel x86 architecture into ARM-based Apple Silicon architecture. For the uninitiated, Rosetta 2 is the translation layer that allows you to use Intel-based apps on Apple Silicon Macs. The reality will likely be different, but 80% efficient x86 on ARM emulation is something to desire especially in the server world.After the introduction of Rosetta in 2006 during the PowerPC-Intel transition, Apple has announced a much-improved Rosetta 2 in 2020 for seamless Intel-Apple Silicon transition.

Therefore, in two years, we might all be running x86 legacy software on our octal-core ARM computers and enjoying the advantages of a lower price and a higher efficiency. This is also the reason for us to estimate project release in late 2014.' The major concern for us is lack of software developers with binary translation expertise. Implementation of an optimization process will start in parallel later this year - we are expecting both parts be ready in the end of 2014. 'Currently, we are creating a binary translator which allows us to run applications. If that advantage usually ranges between 50% and 90% in certain scenarios, a 50% efficient emulator will likely halve that performance per watt advantage, but the ARM hardware will still have the upper hand.ДЄnatoly Konukhov, member of the Elbrus Technologies team and former team leader at Parallels commented on the new software technologies as follows: The emulator makes the solution available today with no extra costs except the cost for the emulating program.Д®lbrus Technologies might also be considering the superior performance per watt that ARM offers. So what if the performance is only 40% and a properly ported application would have offered more performance. The main issue is that youвЂ™re waiting for your much-needed software tool to become available and youвЂ™re also paying a whole team for thousands of work hours to recode your software.ДЄll these costs are really not desirable especially when the end performance is lower so, when a company offers you a simple emulator that will run your software on ARM today with no recoding or optimization needed, youвЂ™ll most certainly be interested. Once an x86 software is deemed essential and porting is the chosen method of action, youвЂ™ll likely have to wait weeks if not months for your software team to recode and optimize the application only to find out that youвЂ™re only getting 60% of the performance your x86 server was able give you. Porting and optimizing software is a costly and complicated affair. What Elbrus Technologies is currently offering is an emulator that will run any of your x86 applications on an ARM computer with roughly 40% of the performance youвЂ™ll get from a completely ARM optimized version of that software.

Porting programs is a really complex operation and the results obtained are often less than perfect as the program can be made compatible with a different hardware architecture, but the same performance is rarely achieved.ДЄn improvement of performance is even less common.

Elbrus Technologies, an American company founded by a Russian software development team has announced that they are working on a special x86 on ARM emulator that will allow existing Windows software to run on ARM servers and computers without any need to modify, optimize or recode the used program.
