 Samsung Galaxy S3 powered by Exynos 4 Quad processor : Samsung Electronics 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 CORTEX 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 Exynos 4 Quad processor is scheduled to be adopted first into the Samsung Galaxy S3 smartphone.

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 mobile games, video editing, and calculation-intensive simulation.
Exynos 4 Quad processor
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% 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.
High-quality camera functionality
Having identical form factor measurements (12mm x 12mm x 1.37mm), 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 was architected to drive up to 1366 x 768 (WXGA) display and 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 digital 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.
