This report presents our first trial to apply a Network-on-Chip (NoC)
architecture to a gasoline engine control, one of automotive
applications that require high dependability.
CPU cores in our NoC platform implement
a production grade Electric Control Unit (ECU) for a gasoline
engine, and compute some of the critical control outputs including
injection timing, injection duration and ignition timing from the
corresponding sensor data.
In a NoC based architecture, connection
between sensors/actuators and ECUs can be flexible. This makes it easy
for our NoC platform to control an engine with
high dependability, by having redundant CPU cores where
the engine control application software is redundantly stored and an external IO
core that dispatches the computation to a non-faulty CPU based on online
failure detection.
We demonstrated that the engine controlled by our NoC based ECUs
could be kept running properly despite a (simulated) failure of
one of the CPU cores. |
