QNX delivers determinism not just at the application level, but also within all subsystems, through nested hardware interrupts, preemptive prioritized context switching, and priority inheritance. Memory is Money Automakers deal in volumes - large volumes. Unfortunately, conventional OSs consume at least several megabytes of memory simply to provide the OS and GUI services required for DIS products. Like QNX itself, this windowing system starts with a tiny microkernel and provides most GUI services through optional processes. As a result, developers can include only the GUI services their memory-constrained systems require, and no more.
All applications are fully customizable, allowing the manufacturer to create a unique look and feel.
