Avid E3 Engine Internals

From musings of k8
Jump to: navigation, search


The Avid E3 Engine contains a daughter board, the Diamond Platform controller (see Avid Diamond Platform) running Linux that bridges the physical audio connections of the E3 engine with the AVB protocol stack.

It also contains a second daughter board, the Feroceon-KW controller (see Avid Feroceon-KW) running Linux that enables the Ethernet switching functionality of the AVB ports (ports A, B, and C). It also provides an EUCON proxy for connecting to the Avid S3 Console.

The fourth Ethernet port is controlled by Windows.

This is a rough block diagram based on my current understanding from my digging.

Many thanks to Karl Noon (audio@noon.ruhr), who is the person who supplied me with just enough info that I was able to find my way into the internals of the Avid S3L.
