The world’s first COTS DO-178B qualifiable HMI tool.
Qualifiable to RTCA DO-178B level A, VAPS QCG is designed to generate code in a consistent and reliable way and eliminates the need for manual coding of VAPS graphics, logic, and behavior.
VAPS QCG dramatically shortens the time and effort required for producing qualifiable code for embedded displays.
Qualifiable to RTCAlevel A, VAPS QCG is a code generation solution for deploying VAPS applications to a safety critical , including aircraft cockpit display systems. Since VAPS QCG is coupled with the VAPS graphical design environment, this tool enables graphics software generated from a VAPS application to be certified with a minimum of effort.
By greatly reducing the effort required within the software design, coding, and testing phases of the graphics display development lifecycle, VAPS QCG dramatically shortens the time required for developing certifiable embedded software products. Presagis also offers a range of Professional Services and DO-178B consultants to help you to quickly get your certification project up and running.
Designed to generate code in a consistent and reliable way, VAPS QCG eliminates the need for manual coding of VAPS graphics, logic and behavior and includes the following functionality:
The input object is used to handle the events (such as press, release, move, etc) from an input device (mouse or similar). The type of events handled by the input object can be customised, i.e the user can decide which events will be supported by supplying the customised user code for handling the events. The runtime will process hit detection for pointer events and return the object(s), if any, that has an active area that intersects with the position at which the pointer event occurred.
The texture fonts feature refers to using OpenGL textures to draw raster (bitmap) text. Using textures as opposed to drawing with gIBitmap provides more functionality, such as rotation and some scaling. It also greatly reduces bus traffic, as the textures are already loaded into the graphics accelerator memory.
Drawing graphics using display lists is supported in QCG. If a graphical object is flagged as being a display list, specific drawing commands will be code generated. This will result in constructing and drawing a display list that contains all graphics within the graphical object. Fonts and circles can be optionally drawn with display lists.
The Frame VPL (visual priority level) sorting algorithm has been updated and now uses a more optimal sorting algorithm that will significantly improve both initialization used and runtime performance.
Previously, the GDI driver function for each GDI object was looked up at each call to a GDI object driver function. In 2.2, the driver for each object is only looked up at initialization time and is then cached for use on each call. This can save significant CPU cycles.
