Hantro G-Series 1 Video Decoder
Multi-format configurable hardware design for multimedia integrated circuits (ICs)
Decode WebM Video Content With Full Hardware Acceleration!
The Hantro G-Series 1 multi-format RTL hardware decoder brings an unprecedented level of format and resolution support to enable all kinds of video applications. It is the first hardware decoder in the market to encompass full WebM video support, significantly extending the video playback time of Internet-connected and HTML5-enabled battery operated devices.
Intended for chipsets targeting multimedia devices (DVD/Blu-ray players, HD set-top boxes, mobile devices, netbooks, etc.), the Hantro G-Series 1 is built on silicon-proven designs deployed in millions of chips worldwide, and provides semiconductor manufacturers with a minimal risk solution for integrating high performance video capability to their chipsets.
The video decoder design is exceptionally fast, requiring less than 100MHz clock frequency to decode 1080p video at 30 fps, and can even achieve 60fps decode for 1080p video. 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.
Compared to commercially available software solutions for digital signal processors (DSPs), the G-Series 1 is more power efficient, consuming less than 50 milliwatts for HD video decoding, and less than 10 milliwatts for SD video.
Design innovations optimize silicon utilization and integration
- Easy back-end: Single clock domain;low number of isolated single port SRAM and clock gating elements; no dual port memories.
- Format and post-processing configuration: optimize silicon area by selecting only the formats and functions you need for your SoC design.
- Performance configuration: choose internal memory size according to your resolution requirement - from QCIF to 1080p.
- Target SoC configuration: choose the bus protocol interface from AHB, AXI, OCP and APB.
- Easy application development: simple application programming interface with OpenMax, multimedia framework plug-ins available.
