Samsung Electronics Co. Ltd has unleashed what it touts as the industry's first dual-core processor samples based on the ARM Cortex-A15 core. According to the company, the 2GHz dual-core Exynos 5250 uses 32nm high-k metal gate (HKMG) low-power process technology and is geared for high-end tablets.

The ARM Cortex-A15 based application processor can process 14 billion instructions per second (DMIPS, Dhrystone million instructions per second) at 2GHz. The performance nearly doubles the current Cortex-A9-based dual-core processor running at 1.5GHz capable of 7,500 DMIPS, noted the company.

The Exynos 5250 was designed to drive up to 2560x1600 (WQXGA) display that reflects the significance of advanced display technology transitioning toward ever higher and sharper resolutions, Samsung said. These leading-edge 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 company claimed.

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 or e-books.

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 playback. Moreover, the Exynos 5250 features a doubled memory bandwidth of 12.8GB/s. This memory bandwidth is a key requirement for a processor to support WQXGA resolution displays.

Samsung's Exynos 5250 offers a host of peripheral functions including an embedded image signal processor enabling 8MP resolution images at 30fps and a full HD 60fps video hardware codec engine for high resolution 1080p video recording and playback. It also has an HDMI 1.4 interface for sharp and crisp multimedia content transmission, along with a diverse scope of embedded booting device interfaces such as SATA, UART, USB and external ports such as USB3.0, eMMC4.5 and eSD3.0.

The Exynos 5250 is sampling to customers and is scheduled for mass-production in 2Q12.
