RK3128 is a high performance Quad-core application processor for smart TV-Box. Especially it is a high-integration and cost efficient SOC for 1080P H.265 TV-Box. Quad-core Cortex-A7 is integrates with separately Neon and FPU coprocessor, also shared 256KB L2 Cache. Mali400 MP2 GPU is embedded to support smoothly high-resolution (1080p) display and mainstream game.
Lots of high-performance interface to get very flexible solution, such as multi-pipe display with HDMI1.4, TV Encoder. Crypto hardware is integrated for support security BOOT. 32bits DDR3/LPDDR2 provides high memory bandwidths for high-performance. HEVC hardware is integrated for support 1080P H.265 video.


RK3128 have very good Linux support including U-Boot, kernel, graphics, video decoder and encoder.
