Chapter 1 Introduction
1.1 Overview
RK2818 is a highly-integrated, high-performance, low-power digital multimedia
processor which is based on Dual Core (DSP+CPU) architecture with hardware accelerator.
It is designed for high-end multimedia product applications such as MID, AP, GPS and
Mobile TV etc.
RK2818 can support decode for various types of video standards such as H.264
/RMVB/MPEG-4/AVS/VC1/MPEG-2 by software and dedicated coprocessors, and encode
for some video standards by software. Specially, highest performace for video decode will
reach fluent replay for video with H.264 @ 1280x720 formats. RK2818 also provides
strong graphics/image ability with embedded GPU. By providing a complete set of
peripheral interface, RK2818 can support very flexible applications, including SDRAM/
Mobile SDRAM/DDRII/Mobile DDR, Nor Flash, Nand Flash, LCDC, Sensor, USB OTG
2.0/USB Host 1.0, SD/MMC/SDIO, Wi-Fi, High-speed ADC, I2C, I2S, UART, SPI, PWM etc.
