coprocessor is included . The native clock speed is 560 MHz. ARM rates the performance of the ARM926EJ-S at 1.1 DMIPS/MHz the performance of the Rockchip 2808 when executing ARM instructions is therefore 660DMIPS roughly 26% the speed of Apple's A4 processor.
The DSP coprocessor can support the real-time decoding of 720p video files at bitrates
of up to 2.5Mbit/s.
This chip is the core of many Android and Windows Mobile
mobile internet devices.

VP8 in hardware. It encodes and decodes H264 at 1080p, and most of the standard video formats (MKV, Xvid, H263, AVS, MPEG4, RV, WMV). The GPU is able to render OpenGL
ES 2.0 and OpenVG
at a rate of 60 million polygons per second, six times the power of the iPad GPU. It is compatible with Android 2.3.
Rockchip 27xx series
Rockchip was first known for their RK 27xx series that was very efficient at mp3/mp4 decoding and was integrated in lots of low-cost mp3/mp4 products.Rockchip 2808
This device is a licensed ARM926EJ-S derivative. Along with the ARMARM architecture
ARM is a 32-bit reduced instruction set computer instruction set architecture developed by ARM Holdings. It was named the Advanced RISC Machine, and before that, the Acorn RISC Machine. The ARM architecture is the most widely used 32-bit ISA in numbers produced...

OpenGL
OpenGL is a standard specification defining a cross-language, cross-platform API for writing applications that produce 2D and 3D computer graphics. The interface consists of over 250 different function calls which can be used to draw complex three-dimensional scenes from simple primitives. OpenGL...

OpenVG
OpenVG is a standard API designed for hardware-accelerated 2D vector graphics. It is aimed primarily at mobile phones, media and gaming consoles such as the PlayStation 3, and other consumer electronic devices. It will help manufacturers create flashier user interfaces that are less dependent on...
