Lumissil T31 smart video processors

The VPU (Video Processing Unit) core is a video encoder engine designed to process video streams using the HEVC (ISO/IEC 23008-2 High Efficiency Video Coding) and AVC (ISO/IEC 14496-10 Advanced Video Coding) standards. It also supports still picture encoding using the JPEG standard (ITU T.81). Together with the on-chip video accelerating engine and post image processing unit, T31X family delivers high video performance. The maximum resolution of 2592x2048 in the format of AVC are supported in encoding. up to 40Mbit/s, 2592x1920@25fps. This family supports 3D denoise and HDR/WDR and other ISP functions – all in a compact QFN SOC!
