RK3028 low power, high performance processor solution for tablet BGA
Product Descriptions
RK3026/RK3028Ais a low power, high performance processor solution for tablet, Android Portable GPS and other digital multimedia applications, and integrates Dual-core Cortex-A9 with separatelyNeon and FPU coprocessor ,and also with256KB L2 Cache.
Many embedded powerful hardware engines provide optimized performance for high-end application. RK3026/RK3028A 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 RK3026/RK3028A completely compatible with OpenGL ES1.1 and 2.0, OpenVG1.1 etc. Special 2D hardware engine with MMU will maximize display performance.
RK3026/RK3028A 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 as follows :
This document will provide guideline on how to use RK3028A correctly and efficiently. In them , the chapter 1 and chapter 2 will introduce the features, block diagram, signal descriptions and system usage of RK3028A, the chapter 3 through chapter 5 will describe the function,electricalcharacteristics and hardware guideline.
