AL-D300 Decoder IP

4K/8K Scalable Multi-Format Video Decoding IP Core


AL-D300 is the Allegro DVT’s ultimate multi-format, multi-stream real-time hardware decoder IP core, for all semiconductor manufacturers looking to integrate a high-performance video decoding solutions into their chips.

Built upon a true multi-format architecture, the AL-D300 decoder IP core provides highly scalable solution up to 8K resolution through their multi-core architecture and selectable video codecs.

The AL-D300 decoder IP core also generalizes the ultra-low latency decoding down to sub-frame latency for all mainstream video formats: H.265/HEVC, H.264/AVC and JPEG. With 8-, 10- and 12-bit support and supporting chroma sampling of 4:2:0, 4:2:2 and 4:4:4, this decoder core is truly market leading.
