GStreamer Based Image Signal Processor/Performance/imx8: Difference between revisions

These measurements were taken with the '''top''' app to monitor the behavior of the pipeline while running.

[[File:Cpu.png|frame|center|CPU usage for '''CSC''' element]]

[[File:Memo.png|frame|center|Memory bandwidth consumption by '''CSC''' element]]

These measurements were taken using some '''timestamps''' before and after the processing to measure just the execution time for the kernel algorithm on each frame and hence avoiding possible false measurements from the GStreamer plugin.  

 

[[File:Extime.png|frame|center|Execution time for different resolutions with the '''CSC''' element]]

These measurements were taken with the '''gst-perf''' tool to monitor the behavior of the pipeline while running. When using videotestsrc we are able to process as many buffers as the element can handle, hence the maximum value reported.  

[[File:Framerate.png|frame|center|Framerate for different resolutions with the '''CSC''' element]]

These measurements were taken with the '''top''' app to monitor the behavior of the pipeline while running.

[[File:cpu-usage-debayer.png|frame|center|CPU usage for '''debayer''' element]]

[[File:memory-debayer.png|frame|center|Memory bandwidth consumption by '''debayer''' element]]

These measurements were taken using some '''timestamps''' before and after the processing to measure just the execution time for the kernel algorithm on each frame and hence avoiding possible false measurements from the GStreamer plugin.

[[File:exec-time-debayer.png|frame|center|Execution time for different resolutions with the '''debayer''' element]]

These measurements were taken with the '''gst-perf''' tool to monitor the behavior of the pipeline while running. When using videotestsrc we are able to process as many buffers as the element can handle, hence the maximum value reported.  

[[File:max-framerate-debayer.png|frame|center|Framerate for different resolutions with the '''debayer''' element]]

These measurements were taken with the '''top''' app to monitor the behavior of the pipeline while running.

[[File:CPU usage for AWB.png|frame|center|CPU usage for '''AWB''' element]]

These measurements were taken with '''perf stat''' linux tool to measure the bandwidth needed by the pipeline.

[[File:Memory Bandwidth for AWB.png|frame|center|Memory bandwidth consumption by '''AWB''' element]]

These measurements were taken using some '''timestamps''' before and after the processing to measure just the execution time for the kernel algorithm on each frame and hence avoiding possible false measurements from the GStreamer plugin.

These measurements were taken with the '''gst-perf''' tool to monitor the behavior of the pipeline while running. When using videotestsrc we are able to process as many buffers as the element can handle, hence the maximum value reported.  

[[File:Maximum Framerate AWB.png|frame|center|Framerate for different resolutions with the '''AWB''' element]]

These measurements were taken with the '''top''' app to monitor the behavior of the pipeline while running.

[[File:CPU usage Eq.png|frame|center|CPU usage for '''Histogram Equalization''' element]]

These measurements were taken with '''perf stat''' linux tool to measure the bandwidth needed by the pipeline.

[[File:Memory Bandwidth Eq.png|frame|center|Memory bandwidth consumption by '''Histogram Equalization''' element]]
