A Modern Embedded Product Platform
summary
Barco builds a reusable embedded projector platform that runs Linux and uses an FPGA for real‑time image pipeline while the CPU handles control; the CPU is a quad-core 1.2GHz ARM A7 with 1 GB RAM and the imager is a DMD of about 4 million mirrors. Design choices include a user-space hardware access layer, code‑generated IPC stubs/skeletons, a facade exposing JSON‑RPC over UNIX domain socket, an event loop with RAII subscription scopes and async deferred/promise patterns in C++ — production code used across products.
