A processing system includes configuration registers and a non-volatile memory with memory slots storing configuration data bits and error detection bits. A hardware configuration circuit sequentially reads the data bits from the non-volatile memory for storage in respective configuration registers by: receiving bits from a current memory slot; selectively asserting an error signal in response to comparison of received error detection bits with calculated error detection bits; storing the received bits to temporary registers where the error signal deasserted and other otherwise asserting a further error signal where the error signal is asserted. Otherwise, predetermined configuration data is stored to the temporary registers. The content of the temporary registers is then sequentially stored to the configuration registers. A reset signal is generated in response to the further error signal to reset the configuration registers.

Processing system, related integrated circuit and method

An architecture of an ignition and/or injection managing system for an internal combustion engine, of the type structured to cooperate with an electronic engine control unit. Also included is an electronic device architecture for determining the operating phase of an internal combustion motor, based on an input signal issued from a sensor of a phonic wheel associated with the motor camshaft, so as to release the electronic motor control unit from monitoring the phonic wheel signal, in order to lighten its computational load, and to enable the processing of the signal issuing from a variety of the phonic wheels. The device has the task of calculating the angular position of the drive shaft by analyzing the signal transmitted by the tone wheel of the drive shaft. A module is provided that is capable of emitting an interrupt signal toward the control unit on the basis of received signals.
