Description
Summary:Software used in avionics must comply with strict aviation standards. The aviation standard ARINC 661 defines the interfaces and a number of specific requirements for the information display system in the cockpit. Due to these requirements, the task of ensuring an acceptable rendering speed on the promising i.MX6 platform with reduced power consumption arises. The development of the OpenGL SC (Safety Critical) graphics library that works in the JetOS real-time avionics operating system and accomplishes this task is considered. It displays information generated in accordance with the ARINC 661 standard using the hardware support of the Vivante GPU. An efficient rendering acceleration approach is proposed and implemented. First of all, calls to OpenGL functions were optimized in the display system that works in accordance with the standard. However, such a modification incurs significant expenses for certifying the entire display system. For this reason, optimization was implemented in a special intermediate module. The proposed approach makes it possible to achieve a rendering speed that is acceptable for the pilot’s display in the cockpit.
