Among the personal computer 64-bit operating systems are nothing new. Both Windows, OS X and Linux are available in 64-bit versions for a long time. Mobile systems are still available in 32-bit versions. Android is not much different from the competition. This situation may change dramatically, however, as the repository on GitHub for Android makes some interesting changes that can significantly closer to the green robot 64-bit version.
Ron Amadeo, acting as editor for the website Ars Technica, informed about the changes that observed on Github company. Comments on commitach mention the extension AArch64 ARMv8 architecture. Android, being an open system repeatedly witnessed the inclusion of code from developers unrelated to Google. The presence of employee names California corporation, however, may indicate that Google took itself seriously for the implementation of new technology to Android.
Meanwhile, two weeks ago, Intel announced that it will release Android x86-64 on their latest Atom processors Bay Trail. Devices operating under the control of Intel is not too much, and the vast majority of phones and tablets still uses the ARM architecture.
It must be remembered, however, that 64-bit arithmetic and address spaces microprocessors are nothing new. ARM architecture is derived from RISC, and it is the processor of this family, such as the HP PA-RISC and Sun SPARC debuted the first technical implementations of 64-bit extensions. Same ARM cores lived to see such an extension until 2011, with the release of ARMv8-A architecture, which adds, among others, A64 instruction set. Most importantly, this extension which was used by Apple in the iPhone 5S system, allows you to run 32-bit applications on 64-bit and 32-bit control systems for 64-bit hypervisors. Currently, these capabilities allow you to use iOS7 and the Linux kernel version 3.7.
What do you expect after 64-bit Android? One of the most “noticeable” changes will be able to use 4 GB (or more) of memory. Currently, the largest RAM memories can boast only a few devices like the Samsung Galaxy Note 3 The use of such a large amount of RAM will enable new applications and games to use the full potential of 64-bit technology. But this is not the rule, because a lot of great applications do not need and will not need as many gigabytes of memory. The arms race will, however, lasted at best.
Another thing is to use processors based on the latest architecture ARMv8-A, which is much more efficient than their predecessors. Google has been somewhat forced to change the architecture, as the biggest competitor, Apple introduced the iPhone 5S, which is based on ARMv8-A’s. 64-bit mobile operating systems are inevitable and only a matter of time before producing the first phone with 64-bit Windows Phone. Production of processors that are able to take full advantage of the technology is planned for the second half of the year. Then it should go to the sale devices equipped with processors based on the architecture of the Cortex A53 and A57. There is little evidence that the flagship of the new processors went on sale before 2015. Qualcomm Snapdragon 805, which will be a top model processors, will still handle only 32-bits. You can expect the first devices with the processor in the third quarter of the year.
Google is still plenty of time to upgrade the version of Android to x64. It is possible that the first high-end smartphones and tablets by 2015 will be released with Android ?wie?utkim based on the new technology. Google may, however, do everything to the latest Nexus (unless remain Nexus), which is likely to be presented in the second half of the year, supported by 64 bits. However, this is conjecture uncovered by the facts.
process of implementing a new technology should take Google several months and coincides with the release of probably the newest iPhone with full support for 64-bit. This movement is nothing extremely surprising. The only thing that remains for us, the gray-users is to wait and watch the repositories of Android in search of interesting changes.
