Library API performance
 | lleon: Please, specify: which performance metrics and the tools used for recording, tolerance of the framerate (please remove this box when addressed) |
To measure the CUDA ISP API performance, we built a simple example (provided upon request) that iterates over the apply methods and records performance metrics for each iteration. We recorded the duration of each apply method separately. We then recorded the CPU and GPU usage, as well as the CPU RAM and GPU RAM usage for the complete processing pipeline running at 30 fps. We recorded the performance statistics for 1080p and 4K buffers. We recorded the performance on a Jetson Nano, Jetson Xavier NX, Jetson Xavier AGX, and Jetson AGX Orin.
| lleon: Please, specify: environment (jetpack) and power mode (please remove this box when addressed) |
| lleon: Could you put a theoretical framerate calculated from the processing time. You can put that into (). i.e. cudashift 60 (16K) (please remove this box when addressed) |
The following table summarizes CUDA ISP's performance results:
