The increasing complexity of embedded systems has significantly raised the expectations for graphical user interfaces. Modern applications require smooth animations, real-time responsiveness, and efficient rendering often within constrained hardware environments. As a result, selecting the right GUI framework has become a critical engineering decision.
This white paper presents a structured evaluation of GUI frameworks on an STM32U5-based platform, using consistent benchmarking methodologies and real-world UI scenarios. By analyzing performance metrics such as FPS, CPU utilization, memory usage, and render time, the study provides insights into how different frameworks behave under practical workloads.
From rendering pipelines and memory strategies to development workflows and portability considerations, this paper highlights key technical aspects that influence framework selection in embedded systems.
Key topics covered:
- Benchmarking methodology using a common UI implementation
- Performance analysis across video, 2D, SVG, and text rendering scenarios
- Rendering architecture and memory management approaches
- Developer workflows and integration considerations
- System-level factors affecting scalability and portability
This white paper is intended for embedded engineers, system architects, and product teams involved in designing and optimizing graphical interfaces for embedded platforms.
