  • Circuit for monitoring a microprocessor and analysis tool and inputs/outputs thereof
    Patent number: 7673121
    Abstract: A method for the transmission of digital messages by the output terminals of a monitoring circuit which is integrated into a microprocessor, the digital messages being representative of first specific events which are dependent on the execution of a series of instructions by the microprocessor.
    Type: Grant

  • Transmission of a digital message between a microprocessor monitoring circuit and an analysis tool
    Publication number: 20060155971
    Abstract: The invention relates to a method for the transmission of digital messages by a monitoring circuit (18) which is integrated into a microprocessor (12), said method being performed during the execution of a series of instructions by the microprocessor. Moreover, at least one of said digital messages represents the detection of a jump in the execution of the series of instructions from a source instruction to a destination instruction. The inventive method consists in determining whether or not the jump is associated with a jump instruction from the series of instructions for which the address of the jump destination instruction is explicitly indicated in the instruction. If the answer is in the affirmative, a first value is allocated to a first set of bits or, if the answer is in the negative, a second value is allocated to the first set of bits.
