I have to imagine that this is the purview of embedded 2D microprocessors / OSes like Linux4SAM. https://www.microchip.com/en-us/development-tool/linux4sam.org https://www.microchip.com/en-us/development-tool/linux4sam.o... With well made compute modules: https://www.digikey.com/en/products/detail/microchip-technology/ATSAMA5D27-SOM1/8536637 https://www.digikey.com/en/products/detail/microchip-technol... And open reference designs that fit on 4-layer boards (!!!!) despite using DDR2. Though I think most people would be more comfortable with 6-layer boards (which is possible with OSHPark today).
