Abstract
An electronic tracing process includes packing both stall (215) and reason (219) data into a single high priority timing information stream. An integrated circuit includes an electronic processor (110), and a tracing circuit (120) operable to pack both stall and events data into a single timing information stream. Other circuits, processes and systems are also disclosed.
Claims5
An electronic tracing process comprising:
- packing both stall and reason data into a single high priority timing information stream, and
- selectively prioritizing the stall and reason data into the single high priority timing information stream over PC trace and data trace,
- wherein the PC trace includes program flow activity and the data trace includes a trace of instruction bus data and data bus data for tracing load/store data accesses.
