ARM was working with Microsoft to refine Windows RT so that
it could run on CPUs based on its 64bit architecture.
ARM is cooperating with Microsoft to make a version
of Windows RT which will run on the 64bit CPU.
There are a little of detailed news, but it’s said that ARM is
cooperating with Microsoft to make a version of Windows RT which will run on
the 64bit CPU. It will expand the memory capacity of the device and allow them
to improve the operating performance.
Ian Forsyth, program manager at ARM, can’t comment upon the
specific release date of Windows RT 64bit version, but it’s said that ARM is
continuing on working with software partners to add the 64bit support.
“ARM works with all the operating system partners and its
ecosystem to inform them of the next generations of technology and allow their
support,” said Nandan Nayampally, marketing manager of the ARM microprocessor.
A spokesperson of Microsoft refuses to give detailed
comments of Windows RT 64bit version. He lets us know that there is nothing to
share at this point.
Windows RT
At the end of October, Microsoft released Windows RT, a
32bit operating system which worked with ARM microprocessor and Windows 8, the 64bit
operating system works with x86 microprocessor. ARM now announced the designs
of the first 64bit microprocessor: Cortex-A57 and Cortex-A53 based on Armv8 architecture
of ARM. This chip manufacturer said that it hoped the server and mobile devices
based on CPU would be released in 2014.

Today, Windows RT runs on tablets with 32bit microprocessor
from nVidia and Qualcomm. Microsoft Surface tablet and Vivo Tab RT of Asus run on
Tegra 3 Quad-core of nVidia; meanwhile XPS 10 of Dell and P8510 Ativ Tab of
Samsung use Snapdragon S4 Quad-core of Qualcomm.
Windows RT 32bit operating system has limited memory
ceiling, and the 64bit version will expand the memory capacity in the tablet as
well as in PC. 64bit version of Windows on ARM will make it equal to Windows 8.
nVidia is developing a microprocessor core based on 64bit architecture
of ARM with the code named of Project Denver. The company refuses to comment
upon the development of 64bit software for Windows.
A spokeswoman of Qualcomm said that the company can’t
comment upon the product plan, especially at this point. However, she lets us
know that Qualcomm is a partner of ARM and they help to find out and judge the emerging
technologies, even the support of 64bit software.
Compatibility
The interest of Microsoft is nothing to be surprised, as the
move toward 64bit seems to be a natural development for ARM and the support
providers, as to x86.
However, the software will need to be written to support the
ARM 64bit command group, and converting many x86 64bit apps will be a
challenge, according to King. The current applications run on the previous
version of Windows can’t run on RT.
“From the pure technological viewpoint, converting many
common x86 apps into ARM is very complicated”, considered King.
There were also questions about how the developers would execute
the move from 32bit to 64bit, King let us know. However, if customers want the
apps, the developers will provide.
“Fortunately, related people have one or several years to
arrange everything”, King concluded.
