+title: Allegro DVT Video IP Decoder Gen 3
+

+
+description:
+ The al300-vdec represents the latest generation of Allegro DVT IP decoding
+ technology, offering significant advancements over its predecessors.
+ This new decoder features enhanced processing capabilities with improved
+ throughput and reduced latency.
+
+ Communication between the host driver software and the MCU is implemented
+ through a specialized mailbox interface mechanism. This mailbox system
+ provides a structured channel for exchanging commands, parameters, and
+ status information between the host CPU and the MCU controlling the codec
+ engines.
