+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.
