Lossless Compression-Video Frame Buffer IP

OverviewFeaturesRequest Datasheet

Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data.

The lossless compression /decompression algorithm. Typical applications include enterprise data storage. The design is fully synchronous and available in multiple configurations varying in bus widths and throughput.


    • Compression scheme is applied to the video frame buffer (DPB)
    • Absolutely lossless
    • Bit exactness between original frame and compressed/decompressed frame
    • Block based compression scheme
    • Significant memory bandwidth reduction
    • 2.5x – 7x depending on content
    • Used within the decoder loop and between decoder and any video processing sink (Display, etc…)
    • Any lossy algorithm (even « visually lossless ») can’t be added in the decoder loop without creating artefacts.
    • Can be coupled with a cache mechanism associated to the decoder motion compensation logic
