Using Advanced Event Triggering to Debug Real-Time Problems in Embedded Systems

As more and more system components become embedded within the system processor chip, new techniques are required for debug. Signals and busses that were historically available for probe connection at external package pins, are now hidden from the users within the processor package. This problem is referred to as vanishing visibility meaning that the user can no longer employ traditional techniques to see into the system activity. To restore visibility, debug triggers such as breakpoints, watchpoints, counters and other debug tools must now also be embedded to allow access to the embedded signals. This application report instructs the user on how to take advantage of the advanced event triggering (AET) embedded components available on TI?s new digital signal processors.
