Processing system, related integrated circuit, device and method

A processing system comprising:

• a plurality of configuration data client circuits, each configuration data client circuit comprising a register, wherein a respective address is associated with each configuration data client circuit and wherein each configuration data client circuit is configured to receive a first data signal providing configuration data addressed to the address associated with the configuration data client circuit, and to store the received configuration data in the register of the configuration data client circuit;
• a hardware circuit configured to change operation as a function of the configuration data stored in the registers of the plurality of configuration data client circuits;
• a non-volatile memory comprising the configuration data for the hardware circuit;
• and
• a hardware configuration circuit configured to read the configuration data from the non-volatile memory and to transmit the configuration data to the plurality of configuration data client circuits;
• wherein the configuration data are stored in the non-volatile memory in the form of data packets comprising an address of a configuration data client circuit selected from the plurality of configuration data client circuits and the respective configuration data to be transmitted to the selected configuration data client circuit;
• wherein each configuration data client circuit comprises a transmitter circuit configured to transmit a second data signal containing the configuration data stored in the respective register and the address associated with the configuration data client circuit to the hardware configuration circuit;
• and
• wherein the hardware configuration circuit comprises a further register and is configured to sequentially read the data packets from the non-volatile memory, and, for at least one of the data packets, to:
• store the configuration data and the address included in each data packet in the further register;
• select a target configuration data client circuit as a function of the address included in the data packet;
• transmit the first data signal having the configuration data included in the data packet to the target configuration data client circuit;
• receive the second data signal having the configuration data stored in the register of the target configuration data client circuit and the respective address associated with the target configuration data client circuit;
• compare the configuration data and address received from the target configuration data client circuit with the configuration data and address stored in the further register, respectively;
• and
• in response to the comparison, generate an error signal when the configuration data and address received from the target configuration data client circuit do not correspond to the configuration data and address stored in the further register.

A method of operating a processing system that includes a non-volatile memory storing configuration data in the form of data packets, each data packet comprising an address of a target configuration data client circuit and configuration data to be transmitted to the target configuration data client circuit, the method comprising:

• sequentially reading the data packets from the non-volatile memory;
• for a first packets storing the configuration data and the address included in the data packet in a register;
• selecting a target configuration data client circuit as a function of the address included in the first data packet;
• transmitting a first data signal that includes the configuration data included in the first data packet to the target configuration data client circuit;
• receiving via a second data signal the configuration data stored in the target configuration data client circuit and the address associated with the target configuration data client circuit;
• comparing the configuration data and address received from the target configuration data client circuit with the configuration data and address stored in the register, respectively;
• and
• in response to the comparison, generating an error signal when the configuration data and address received from the target configuration data client circuit do not correspond to the configuration data and address stored in the register.
