Product Descriptions

RK292X is a low power, high performance processor solution for low-end tablet, Android Portable GPS and other digital multimedia applications, and integrates single-core Cortex-A9 with separately Neon and FPU coprocessor, and also with 128KB L2 Cache.

Many embedded powerful hardware engines provide optimized performance for high-end application. RK292X supports almost full-format video decoder by 1080p@60fps, also support H.264/MVC/VP8 encoder by 1080p@30fps, high-quality JPEG encoder/decoder and special image preprocessor and postprocessor.

Embedded 3D GPU makes RK292X completely compatible with OpenGL ES1.1 and 2.0, OpenVG1.1 etc. Special 2D hardware engine with MMU will maximize display performance.

RK292X has high-performance external memory interface (DDR3/LVDDR3) capable of sustaining demanding memory bandwidths, also provides a complete set of peripheral interface to support very flexible applications.

This document will provide guideline on how to use RK292X correctly and efficiently.

In them, the chapter 1 and chapter 2 will introduce the features, block diagram, signal descriptions and system usage of RK292X, the chapter 3 through chapter 45 will describe the full function of each module in detail.
