Samsung Electronics has started shipping the industry's first
samples of a dual-core ARM Cortex-A15 processor for high-end tablet PCs.
The 2-GHz Exynos 5250 is built on a 32-nm high-k metal gate low-power
process technology and doubles the performance over the previous 1.5-GHz
Cortex-A9 family with 14 bn DMIPS. It is set to go into volume production
in the middle of 2012.
The Exynos 5250 was designed for 2560 x 1600 (WQXGA) resolution
displays which reflects the significance of advanced display technology
transitioning toward ever higher and sharper resolutions. The memory
bandwidth is doubled to 12.8-Gbyte/s, 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 such as reading static web pages
The 3-D graphics processing capabilities includes stereoscopic support
for high end 3D gaming, user-interfacing and 3-D video playback.
It also includes 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, a HDMI 1.4 interface and embedded booting device
interfaces such as SATA, UART, USB and external ports such as USB3.0,
eMMC4.5 and eSD3.0.
"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 for Device Solutions at Samsung
Electronics. "Designers need an application processor platform that
delivers full high definition multimedia capabilities, fast processing
speed and high performance graphics to meet end users' expectation for a
connected life on the go. 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."This article was first published in our sister publication EE Times Europe.Related links and articles:
