瑞昱RTD1296应用框图

瑞昱Realtek RTD1296主控芯片具有独立安全操作系统的可信执行环境，VP9和H.265解码直至超高清，全H.264高清媒体解码和多格式编码，无线/有线网络，HDMI接收机，数字电视和一套全面的集高速外围设备。

RTD1296作为IPv 6 1WAN-2LAN路由器运行，配备高性能四核CPU ARM Cortex-A53，嵌入1M L2缓存。RTD1296还集成了高效的ARM t 820图形处理单元(GPU)，以加速2D和3D图形处理，实现了与马里-450 8核配置相媲美的性能。为了加速OSD和2D用户界面，the内置的RTD 1296流引擎提供了常用的绘图功能。cpu专门用于应用程序，而rtd 1296的大部分功能使用独立的硬件电路。提供高效优化的系统。RTD 1296的视频DSP致力于处理、解码和编码各种格式的视频流，例如解码4K2KH.265、全高清。MPEG 1/2/4/H.264 MVC，AVC/VC-1，VP8，AVS，AVS Plus，HDJPEG等。视频解码和编码可以同时运行。

此外，RTD1296的视频后处理由一个视频处理子系统处理，该子系统支持3D去隔行、视频扩展到4K2K等。音频解码由能够解码一组音频格式的音频DSP，例如DTS HD、杜比数字+、TrueHD和其他流行格式。音频DSP还执行音频后处理。

RTD1296为丰富的操作系统提供了一个安全的环境，将UHD和HDR内容带到大屏幕上。安全的视频路径和安全的存储对于系统的安全至关重要。随着ARM Trustzone的部署和专有安全机制的实施，RTD1296保护视频和高度机密的信息免受泄漏。独立安全操作系统在RTD 1296上运行。此外，rtd1296硬件还提供了一个密码引擎、真正的随机数生成器和足够的一次性可编程rom(Otp)空间，这是一个LSO是可信执行环境的重要元素。
