Performance Analysis of 2D Graphics Rendering in LVGL Based on ARM Mali G31 GPU

The Light and Versatile Graphics Library (LVGL), a lightweight application display framework, is extensively employed in embedded systems. It inherently supports CPU - based rendering and is also capable of leveraging GPU - based rendering. The 2D display of LVGL finds broad applications. As the complexity of the graphical interface escalates and the demand for dynamic screen presentation surges, the need for enhanced rendering efficiency becomes more pronounced. This paper elucidates multiple 2D screen rendering schemes on the ARM Mali G31 graphics platform. These schemes are then applied to conduct display performance tests on open - source LVGL applications. The test results are presented, and through in - depth analysis, the optimal practical solution is proposed, aiming to enhance the 2D screen display performance.
