A communication architecture (1) of a train in which at least one central processing unit (3) arranged in a train carriage is interconnected through a communication network (5) of the train with a plurality of peripheral processing units (6). The central processing unit (3) is provided on a single board (7) with: a processor (10) designed to process data associated with an SIL 0 safety level; a coprocessor (12) designed to process data associated with an SIL 1-SIL 2 safety level; an internal bus (14) built on the board (7) and configured to allow a two-way data communication between the processor (10) and the coprocessor (12); an interface (16) for the communication network (5) of the train. The coprocessor (12) is designed to be programmed in a reconfigurable manner with a software (18) that allows the validation and encoding of data coming from the processor (10) according to a safety protocol.
