1. A vehicle-mounted information processing apparatus that is mounted in a vehicle and comprises:
a plurality of processing units that perform processing in parallel or pseudo-parallel;
a shared storage unit that is accessible by the plurality of processing units; and
a detection unit that detects an abnormality at the shared storage unit,
wherein the processing units each include a communication unit that performs communication via a communication line, and
the plurality of processing units exchange information with each other based upon the detection of the detection unit, wherein when no abnormality is detected at the shared storage unit the plurality of processing units exchange information via the shared storage unit, and when the detection unit has detected an abnormality at the shared storage unit the plurality of processing units bypass the shared storage unit and exchange information through the communication line using the communication units.
