Hantro G1 multi-format hardware decoder brings an unprecedented level of format and resolution support to enable all kinds of video applications. It is also the first hardware decoder in the market to support full WebM (VP8) decoding.
Intended for chips powering multimedia devices (mobile phones, portable media players, tablets/netbooks, DVD/Blu-ray players, STB, car infotainment, etc.), Hantro G1 is built on silicon-proven designs deployed in hundreds of millions of chips worldwide and thus, provides semiconductor manufacturers with a minimal risk solution for integrating high performance video capability into their chips.
Hantro G1 decoder design is exceptionally fast, requiring around 100MHz clock frequency to decode 1080p video at 30 fps, and can achieve 60fps decode for 1080p video in real life conditions. The core supports unlimited multi-format, multi-channel decoding, enabling simultaneous playback of up to ten SD streams. It uses unique pre-fetching and buffering mechanisms to enable smooth operation with low-end SDRAMs, realizing significant savings in power and overall chip design and manufacturing costs.
