Beirut, Lebanon (May, 2012) Samsung Electronics Co. Ltd., a world leader in advanced semiconductor solutions, introduced the industrys 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 smartphones 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.
The quad-core processor offers phenomenal multitasking abilities surpassing any single or dual application processor. Since all the cores must share a single battery, the power management and efficiency in the limited battery capacity are indispensable for mobile computing devices, said Taehoon Kim, vice president of System LSI marketing, Device Solutions, Samsung Electronics.Given the diverse functionalities consumers are demanding from their mobile devices today, the Exynos 4 Quad meets those high-performance needs while keeping power consumption very low.
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.
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 Dual 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 Dual, 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.
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 Samsungs next Galaxy smartphone that will officially be announced in May. Samsungs Exynos 4 Quad is also sampling to other major handset makers.
