Avivo HD Video and Display Engine
  • Motion Video Acceleration for HD DVD/Blu-ray technology
    • Dedicated UVD (Unified Video Decoder) hardware for H.264 and VC-1 decode:
    • H.264 implementation is based on the ISO/IEC 14496-10 spec.
    • VC-1 implementation is based on the SMPTE 421M spec.
  • Video scaling and fully programmable YCrCb to RGB color space conversion for full-screen / full-speed video playback and fully adjustable color controls.
  • MPEG1/2/4 decode and encode acceleration:
    • Hardware motion compensation
    • iDCT/DCT and color space conversion
    • HW DXVA parser support for iDCT
    • MPEG-4 Simple Profile support
  • All-format DTV/HDTV decoding.
  • Supports top quality DVD and time-shifted SDTV/HDTV television playback with the lowest CPU usage.
  • Adaptive de-interlacing filter
  • Advanced Video Processor (AVP)
    • A memory to memory advanced video processor. Processing includes color space conversion, chroma subsampling format conversion, horizontal and vertical scaling, directional deinterlacing, and gamma correction, all in one pass. AVP offloads format conversion, deinterlacing and scaling tasks from the 3D engine, allowing for reduced memory bandwidth usage, ALU load, and power consumption.
Power Management Features
  • Single chip solution in 65nm, 0.9V-1.2V CMOS technology.
  • Full ACPI 1.0b, OnNow, and IAPC (Instantly Available PC) power management.
  • Static and dynamic power management support (APM as well as ACPI) with full VESA DPM and Energy Star support.
  • Full PowerPlay 7.0 support.
  • The chip power management support logic supports four device power states - On,Standby, Suspend and Off - defined for the OnNow architecture. Each power state can be achieved by software control bits.
  • Clocks to every major functional block are controlled by a unique dynamic clock switching technique which is completely transparent to the software. By turning off the clock to the block that is idle or not used at that point, the power consumption is significantly reduced during normal operation.
