The present invention relates to a method () for controlling an integrated circuit () comprising a microprocessor, in which the integrated circuit () is configured to execute by default a general program, said integrated circuit being controlled by activation of a mode of operation of the integrated circuit, called 'bootstrap mode', in which said integrated circuit () executes a program for loading a specific program to be executed. The method () comprises:

Method for controlling an integrated circuit, integrated circuit and computer including an integrated circuit

The invention relates to a method for determining the energy (KNKE) of the knock of an internal combustion engine, using an analog signal supplied by a sensor fixed to the engine. The inventive method includes the following steps: a) the analog signal is shaped, b) the analog signal is converted into a sequence of digital samples, c) the signal is subjected to digital filtering, and d) the signal is adjusted and e) integrated. According to the method: i) the shaping of the analog signal includes combining the signal with a continuous component (Vcnf) adapted to render the shaped signal a positive signal or a zero signal, and ii) the digital filtering is carried out by a band-pass filter with an infinite impulse response, the transfer function thereof including a zero for the zero frequencies.
