| Abstract: | The NoC techniques changes on-chip communication in a SoC dramatically. As a result, current tracing techniques are not readily applicable to NoC-based systems where the transmission of traced data requires new concerns due to totally different communication mechanism. An in-depth analysis of ARM coresight trace architecture shows new challenges. It analyzes the difficulty of real time data transmission tracking in NoC, and proposes the solution which is verified by experimental simulations. |
| Keywords: | real time tracing tracing link multiplexing tracing data flow control |
