Samsung unveils the first ARM Cortex-A15 processor samples for tablet PCs


Samsung Electronics introduced the
industry’s first dual-core processor, Exynos 5250, based on ARM Cortex-A15 core
for high-end tablets.


Samsung’s newest 2GHz dual-core Exynos 5250
utilizes 32nm high-k metal gate low-power process technology and will offer
system-level designers an exciting new solution intended to meet the
graphic-intensive, power-efficient requirements of these next-generation mobile


The Exynos 5250 is capable of processing 14
billion instructions per second (DMIPS, Dhrystone million instructions per
second) at 2.0GHz, nearly doubling the performance over a current
Cortex-A9-based dual core processor running at 1.5GHz capable of 7,500 DMIPS.


“The ARM Cortex-A15 brings
unparalleled performance to our Exynos processor family and the exploding
mobile marketplace,” said Dojun Rhee, vice president of System LSI
marketing, Device Solutions, Samsung Electronics.


The Exynos 5250 is designed to drive up to
2560 x 1600 (WQXGA) display, which reflects the significance of advanced
display technology transitioning toward ever higher and sharper resolutions.


These features enable users to enjoy
crisper video images on their mobile devices and deliver readability equivalent
to real paper for an ultimate electronic reading experience.


The Exynos 5250 also features a doubled
memory bandwidth of 12.8 Gigabytes per second (GB/s) compared to current
dual-core processors that support a maximum of 6.4GB/s to enable fast data
processing features, superb 3D graphics and high-resolution display. This
memory bandwidth is a key requirement for a processor to support WQXGA
resolution displays.



To maximize power efficiencies at the
system level, the Exynos 5250 has an embedded DisplayPort (eDP) interface that
is compliant with panel self-refresh technology (PSR) applied to the timing
controller (T-CON).


The embedded PSR technology enables static
images to be refreshed directly from the frame buffer memory incorporated in
the T-CON, resolving the need for regular display refresh instructions to be made
by the application processor in cases.


The 3D graphics processing capabilities,
enhanced by more than four-fold over the 1.5GHz Cortex-A9 dual-core processor,
and a stereoscopic 3D feature raise the bar of user experience on
high-specification 3D gaming, user-interfacing and stereoscopic 3D video


Samsung’s Exynos 5250 also offers a host of
peripheral functions including an embedded image signal processor enabling 8
Megapixel resolution images at 30 frames per second, a full HD 60 frame per second
video hardware codec engine for high resolution 1080p video recording and
playback, an HDMI 1.4 interface for sharp and crisp multimedia content
transmission, along with a diverse scope of embedded booting device interfaces.


“The advanced low-power, high-performance
processor technology of the new Exynos 5250 continues to deliver an
unprecedented level of performance for users to enjoy a completely new mobile
experience,” Rhee added.


Samsung Electronics recently announced
production of its high-performance micro Secure Digital (microSD) cards with
advanced data transfer speeds that support the performance requirements on
fourth generation (4G) smartphones.
