Much like you program any other computer. At my shop we use C, C++ and Ada. Some problems suit themselves well to modeling, so something like Simulink can be used (which translates to C++). What throws people off is usually the fact that these are hard real-time systems (requires a different mindset) and that some functions are distributed across multiple computers.
