Exynos 4 Dual. - New 1.4GHz Per Core Energy Efficient (HKMG Process) 32nm
Samsung’s New Quad-core Application Processor Drives Advanced Feature Sets in Smartphone’s and Tablets
Designed on 32nm HKMG process, new energy-efficient chip exceeds 1.4GHz per core
In Seoul, Korea, April 26, 2012 – Samsung Electronics Co. Ltd., a world leader
in advanced semiconductor solutions, introduced the industry's first quad-core
application processor built on the High-k Metal Gate (HKMG) low-power process
technology. With unprecedented performance capabilities exceeding 1.4GHz based
on the ARM® CORTEXTM A9 quad-core, the powerful, yet energy-efficient Exynos 4
Quad, allows system-level architects to integrate maximized power efficiencies
into Smartphone’s and tablets which enables double the processing power at a 20
percent lower power bill over its predecessor, the 45nm process-based Exynos 4
Dual.
Processing
Multi-core processing delivers enhanced performance, enabling users to
accomplish more tasks in a shorter period of time. For example, a task such as
streaming video can run on one core while the other cores update applications
in the background, connecting to the web and scanning virus-check
simultaneously.
Benefits
Benefitting from a use case where the parallel processing and workload sharing among the four cores is necessary, the Exynos 4 Quad is particular well suited for heavy-load applications such as 3D games, video editing, and calculation-intensive simulation.
Due to its 32nm HKMG low-power process and power-saving design, the Exynos 4 Quad has two-times the processing capability over the 45nm process based Exynos 4 Quad while consuming 20-percent less power. To improve power efficiency, Samsung adopted hot-plug functionality to support on-off switching for each core as well as the per-core dynamic voltage and frequency scaling (DVFS), which offers a dramatic reduction in power consumption by adapting different levels of voltage and frequency when changing workloads.
Having identical form factor measurements (12mm X 12mm X 1.37 mm), the Exynos 4 Quad is pin-to-pin compatible with the 32nm process based Exynos 4 Quad, allowing mobile device designers to immediately adopt the new solution without additional cost, engineering or design efforts.
In addition, the new processor incorporates a full HD 30 frame per second video hardware codec engine for high resolution 1080p video recording and play-back, an embedded image signal processor interface for high-quality camera functionality and an HDMI 1.4 interface for sharp and crisp multimedia content transmission.
Power Management
Samsung developed a power management IC (PMIC),
the S5M8767, as a companion chip to power the Exynos 4 Quad processor. By
integrating various circuitry such as nine highly efficient and programmable
buck converters and 28 low-dropout regulators (LDOs) into the small package of
5.0 mm x 5.0mm x 0.4mm, the S5M8767 is designed to scale up or down the dynamic
voltage depending on the clock speed in 6.25mV step for managing power delivery
and maximizing battery life at the system level.Already in production, the Exynos 4 Quad is scheduled to be adopted first into Samsung's next Galaxy Smartphone that will officially be announced in May. Samsung's Exynos 4 Quad is also sampling to other major handset makers.
Last year, Samsung introduced a new online hub dedicated to its Exynos processor. Designed to facilitate easy communication with industry partners and end users, the new micro-site takes you a step closer to the ultimate experience Exynos delivers; product information, user experience and information on promotion events.
