| description: | |
| The Samsung Exynos542x SoC has a NoC (Network on Chip) Probe for NoC bus. |
| NoC provides the primitive values to get the performance data. The packets |
| that the Network on Chip (NoC) probes detects are transported over the |
| network infrastructure to observer units. You can configure probes to capture |
| packets with header or data on the data request response network, or as |
| traffic debug or statistic collectors. Exynos542x bus has multiple NoC probes |
| to provide bandwidth information about behavior of the SoC that you can use |
| while analyzing system performance. |
