“…However, the use of hardware acceleration provides a higher visualization speed. The achieved visualization speed reported in [6] was not satisfactory for typical aviation applications. Moreover satisfactory speed for most of the analyzed applications was achieved using four processor cores only.…”

“…We succeeded to solve to some extent all the problems indicated in points 1-5 and to implement the hardware OpenGL (HWGL) library based on the MESA package. All aviation applications from [5,6] were successfully executed under JetOS using this library. The size of the library was reduced to ~40 megabytes and ~1600 files.…”

“…The hardware OpenGL SC 1.0.1 library implemented on the basis of the MESA package was tested on the same aviation applications that were used for elaboration of the software library in [6]. These are S_PFD (SSJ-100 Primary Flight Display), M_PFD (MC-21 Primary Flight Display), Counters, GlassCockpit, FlightDisplay and SVS (relief visualization).…”

Table 1 shows the visualization speed (in frames per second) for the software OpenGL (SWGL) from [6] and the hardware OpenGL (HWGL) elaborated by us basing on MESA. Column SWGL 1 presents speed for use of 1 core, while SWGL 4 -4 cores was used.…”

The paper discusses details of the pilot display visualization that uses the hardware acceleration capabilities of the Vivante graphics processor in the JetOS aviation operating system. Previously the OpenGL Safety Critical library was implemented without hardware acceleration. This was done in such a way because software library is easier to certify in accordance with the avionics requirements. But usage of the software OpenGL does not provide acceptable visualization speed for modern Flight Display and 3D relief applications. So more complex visualization approach utilized the GPU acceleration capabilities was elaborated. Although the OpenGL library was implemented for a specific GPU and took into account its specificity, the described approach to adapt the MESA open source library can be used for other GPUs. An effective algorithm for multi-window visualization using the implemented library with hardware acceleration is present. The described approach allows you to achieve the visualization speed acceptable for the pilot display of the aircraft.
