2* Samsung Exynos NoC (Network on Chip) Probe device
3
4The Samsung Exynos542x SoC has NoC (Network on Chip) Probe for NoC bus.
5NoC provides the primitive values to get the performance data. The packets
6that the Network on Chip (NoC) probes detects are transported over
7the network infrastructure to observer units. You can configure probes to
8capture packets with header or data on the data request response network,
9or as traffic debug or statistic collectors. Exynos542x bus has multiple
10NoC probes to provide bandwidth information about behavior of the SoC
11that you can use while analyzing system performance.
