Constrained Data-Age with Job-Level Dependencies: How to Reconcile Tight Bounds and Overheads

Many industrial real-time systems rely on the implicit register communication paradigm to minimize overheads and ease distributed development. Here, tasks follow a simple input-processing-output scheme, and data is passed without synchronization by the last-is-best semantics. In these systems, the age of data is the primary real-time objective, which is defined by data-flow chains that span from t...
