The above table describes the specification of the NVIDIA Jetson AGX Orin Developer Kit.
The following tests were conducted on JetPack 5.0.2 with power mode MAXN.

Test Setup

Test setup
Note
The BVS CA-BN device uses 4-lane PCIe 2.0 on the NVIDIA Jetson AGX Orin.

Additional Settings

Set EMC clocks to Maximum

It is important to set the EMC clock to maximum to ensure reliable data transmission. To do so, call jetson_clocks with sudo credentials via CLI:

$ sudo jetson_clocks
Note
The above command line works only temporarily. The clock will be reset after the next system boot. A systemd service can be used to run the command line permanently at every system boot.

Benchmarks

The following tests have been performed using different de-Bayering scenarios to achieve the max. FPS while maintaining 0 lost images. The CPU load during the acquisition is also documented below.

Scenarios that have been tested are listed as follows:

  1. When de-Bayering is carried out on the camera: The camera delivers RGB8 image data to the host system. This setting results in a lower CPU load but a lower frame rate.
  2. When de-Bayering is carried out on the host system: The camera delivers Bayer8 image data to the host system. The Bayer8 image data then get de-Bayered to RGB8 format on the host system. This setting results in a higher frame rate but a higher CPU load as well.
  3. When no de-Bayering is performed: The camera delivers Bayer8 image data to the host system. No de-Bayering is performed. This settings results in a lower CPU load and a higher frame rate. The behavior is identical to monochrome cameras.
