Abstract
A federated display system includes multiple head down displays (HDD) driven by two or more display processing computers (DPC). Each DPC includes two or more display nodes independently managing display processing, graphics generation, and I/O functionality (either within a single processing unit or a multiprocessor environment). Each display node is linked to a mezzanine control plane (MCP) independent of the display nodes, which MCP includes dedicated optical channels to each member HDD of the system and a switching fabric to control the routing of graphical signals from the graphics generators of each node to the optical channel connected to the desired target HDD. The switching fabric includes a master selector for designating any node of a DPC as a master node capable of controlling the switching fabric via its processing control or graphics generation functions.
