Experimenting with ARM A15? £155 developer's board with Exynos 5520

By , source: Howchip


In a collaboration with Samsung, Howchip.com has created a special development kit for Samsung's Exynos 5 5250 chip, which will be available soon at a price of $ 249 (£155).

The Samsung Exynos 5 5250 dual-core ARM Cortex A15 System-on-Chip is very powerful; the SoC consists of a dual-core CPU and quad-core ARM Mali T604 GPU, a combination capable of reaching up to 72 GFlops. To compare, Apple's A6X, used in the latest iPad, reaches speeds of 50 GFlops. The processor comes clocked at 1.7 GHz, but can be combined with an overdrive of 2 GHz on select models. The chip also contains a low-power Cortex A5 co-processor and an audio co-processor.

The memory interface is of the dual-channel type and is compatible with 32-bits 800 MHz LPDDR3. There's a plethora of interfaces available, but notable are USB 2.0 and 3.0(!), SATA 3.0 and HDMI 1.4. The integrated eDisplayPort connector is capable of producing a 2560x1600 pixel resolution. Dual-display is also supported by the chip, which can even display stereoscopic 3D over HDMI.

The Mali-T604 supports full profile OpenCL 1.1 with double precision floating point, which means that OpenCL code for desktop systems will run flawlessly on this processor. This opens up new opportunities for high-performance software on mobile devices, such as augmented reality applications.

The test board features a 100 Mbit Ethernet connectors, two USB 2.0 Host ports, a USB 2.0 on-the-go port, USB 3.0 connector, RS232 serial connector, HDMI, MicroSD and a SATA 3.0 connector. A soundcard and WiFi/Bluetooth/GPS module are bundled. Optionally, the board can be expanded with an NFC, display and camera module. Android version 4.11r4 is supported on the board. Naturally, Samsung's Exynos 5520 is present, clocked at 1.7 GHz and combined with 2 GB of 800 MHZ LPDDR3.
