Embedding stall and event trace profiling data in the timing stream - extended timing trace circuits, processes, and systems

An electronic tracing process comprising:

• A) packing both stall and reason data into a single high priority timing information stream, the timing information stream having an instruction advance and is divisible by synchronization windows;
• and
• B) in case a reason of stall datum in a previous synchronization window is encoded in a next synchronization window, introducing a timing synchronization to indicate that the reason of stall datum is located in the next synchronization window.
