Greetings
What matters most is, does the selected CPU have hidden secrets? and is the obsolescence manageable?
Most of companies develop their own motherboards around the selected CPU , along the basic operating software, and finally the application.
For the applications,most companies use ADA object oriented language (linux), which is now a standard set by the airframers.
Software and Hardware have to be DO 178B compliant, with the appropriate level (A,B,C,D)
I do agree that today IFE is the most advanced.
I think that an interresting debate would be:
Since there is now a moduler Avionics concept, basically made of mother board on which applications a runing ( instead of recievers...)
would not it be very attempting to develop the software in India, and the Hardware in China for price consideration
