Control system with multiprocessor architecture for an internal combustion powertrain

A control system with multiprocessor architecture for an internal combustion powertrain;

• the control system comprising a computing unit capable of executing both basic control functions of the powertrain and ancillary control functions not directly related to the control of the powertrain;
• the computing unit comprises
• a main processor exclusively dedicated to executing basic functions for controlling the powertrain;
• at least one auxiliary processor dedicated to executing ancillary control functions, wherein the auxiliary processor can execute inter-processor interrupt operations in order to wait for the main processor to complete a particular computing algorithm, and the main processor does not execute inter-processor interrupt operations in order to wait for the auxiliary processor to complete a particular computing algorithm;
• a number of memories;
• a series of peripheral devices;
• at least one peripheral bus connection, to which the peripheral devices are connected;
• and
• a main bus connection through a cross-bar switch of the cross-bar bus type to allow the processors to communicate with the memories and with the peripheral bus connection while avoiding the occurrence of conflicting communication operations.
