    Abstract: A processing system (10a) is described. The processing system (10a) comprises a timer circuit (122) and a processing circuit (110). The timer circuit (122) generates, in response to a clock signal ( CLK ), a system time signal ( GST ) comprising a plurality of bits indicative of a time tick-count. The processing circuit (110) receives the system time signal ( GST ), detects (1102) whether the system time signal ( GST ) reaches or exceeds a given reference value, and starts execution of a given processing operation in response to the detection.
    Specifically, the timer circuit (122) has associated an error code calculation circuit (1230) configured to compute a first set of error detection bits ( EDB ) as a function of the bits of the system time signal (GST). The processing circuit (110) has associated an error detection circuit (1112). The error detection circuit (1112) computes a second set of error detection bits as a function of the bits of said system time signal ( GST ) received, compares the first set of error detection bits ( EDB ) with the second set of error detection bits, and generates an error signal ( ERR2 ) in response to the comparison.

    Abstract: A processing system (10a) is described. The processing system (10a) comprises configuration data clients (112), wherein with each configuration data client (112) is associated a respective address (ADR). The configuration data (CD) for the plurality of configuration data clients (112) are store in a non-volatile memory (104), wherein the configuration data (CD) are stored in the form of data packets (DCF_x, DCF_y, DCF_z) comprising an attribute field identifying the address (ADR) of one of the configuration data clients (112) and the respective configuration data. A hardware configuration module (108) sequentially reads (1080) the data packets from the non-volatile memory (104) and transmit the configuration data (DATA) read to the respective configuration data client (112).
    Specifically, the non-volatile memory (104) comprises first signature data (HASH), wherein the hardware configuration module (108) reads also the first signature data (HASH). Moreover, the processing system (10a) comprises a signature calculation circuit (130) configured to calculate second signature data (HASH') as a function of the respective configuration data (DATA) transmitted to the configuration data clients (112) and/or stored in the configuration data clients (112). Accordingly, a signature verification circuit (132) may compare the first signature data (HASH) with the second signature data (HASH') and possibly generate an error signal (ERR).

    Abstract: The present disclosure relates to a processing system. The processing system comprises a plurality of configuration data clients (112), wherein each configuration data client (112) is configured to receive configuration data (CD) addressed to a respective address and store the configuration data (CD) received in a respective register (118). The processing system comprises also at least one hardware block configured to change operation as a function of the configuration data (CD) stored in the registers (118) of the configuration data clients (112), and a non-volatile memory (104) configured to store the configuration data (CD) for the plurality of configuration data clients (112). Specifically, the configuration data are stored in the form of data packets. A hardware configuration module (108) sequentially reads the data packets from the non-volatile memory (104) and transmit the respective configuration data read from the non-volatile memory (104) to the respective configuration data client (112).
    Specifically, at least one of the configuration data clients (112) is configured to receive a first set of configuration data addressed to the respective address and store (1024) the first set of configuration data received in the respective register (118). Moreover, the configuration data client (112) may receive a second set of configuration data addressed to the respective address. In response to the second set of configuration data, the configuration data client (112) verifies (1022) whether further configuration data may be written to the respective register as a function of at least one type identification signal (TI).
