Who cares ? I never heard the OP make any such constraints. Also as for DSPs, PRU, and the like. You can do similar to adding external processors / boards. This wont work 100% of the time, but it will work for 99.9% of the situations out there.
Very rarely does a dedicated embedded processor have to communicate directly with a host processor because of performance constraints. But I can think of at least one situation.
