RK3188Technical Reference ManualRev 1.2 Chapter 1 Introduction RK3188 is a low power, high performance processor for mobile phones, personal mobile internet device and other digital multimedia applications, and integrates quad-core Cortex-A9 with separately NEONand FPU coprocessor. Many embedded powerful hardware engines provide optimized performance for high-end application. RK3188 supports almost full-format video decoder by 1080p@60fps, also support H.264/MVC/VP8 encoder by 1080p@30fps, high-quality JPEG encoder/decoder, special image preprocessor and postprocessor. Embedded 3D GPU makes RK3188 completely compatible with OpenGL ES2.0 and 1.1, OpenVG 1.1. Special 2D hardware engine with MMU will maximize display performance and provide very smoothly operation. RK3188 has high-performance [ ... ]
