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.
