Tasks of the GPU

  • For „simple“ webpages without 3D-features, the GPU is only used for „blitting“during a process step called „Raster(ization) and Compositing“
  • „blitting“ = fast copy and move of memory objects
  • By this, a strong relief of the CPU can be achieved
  • this should be well possible with the STM32MP1

Performance Tests

"Infragistics Ignite UI" Demo Application

The "Infragistics Ignite UI" is a commercial WebUI framework based on Angular. It has many web controls for many purposes.


It takes approx.3 seconds from menu click until content is fully visible

Profiling with Chromium

Brief summary

  • Webapplications must be optimized for particular embedded system resp. SOC
  • Comprehensive analysis and profiling tools are available
  • Thus, appealing web pages on embedded systems should be possible
  • … where also the “responsiveness" is given
