摘要:
An integrated circuit (101) includes a performance monitoring circuit (107) which includes an adaptive adder circuit coupled to receive a first input signal indicative of a performance parameter of the integrated circuit and to provide a count value as a measure of the probability of the performance parameter. The adaptive adder circuit includes a random number generator circuit (205) providing a random number, a counter circuit (201) providing a count value and a comparator circuit (203) coupled to compare the random number and the count value and to output a compare signal (204) indicative thereof, the compare signal being provided to the counter as an up/down count signal. The adaptive adder circuit also includes a first logic circuit (207) coupled to receive the performance parameter being measured and the compare signal which outputs a first signal which is used for controlling operation of the counter circuit. The counter circuit is responsive to count up or down when the first input signal and the compare signal are at different values and the counter circuit does not count when the first input signal and the compare signal are at the same value.

An approach to determining vehicle usage makes use of a sensor that provides a vibration signal associated with the vehicle, and that vibration signal is used to infer usage. Usage can include distance traveled, optionally associated with particular ranges of speed or road type. In a calibration phase, auxiliary measurements, for instance based on GPS signals, are used to determine a relationship between the vibration signal and usage. In a monitoring phase, the determined relationship is used to infer usage from the vibration signal.

The invention relates to a stochastic-type microprocessor. The microprocessor comprises an elementary stochastic computation module (1) able to receive as input two random and independent binary input signals (A, B) each representing a binary coding of two respective given input probability values, and able to generate as output a random binary output signal (C). The elementary module comprises: - a programmable logic unit (2), able to combine two input signals (A, B) to generate an output signal (C); an addressable memory (3), able to store an output probability value coded by an output signal (C) generated by the logic unit (2); - a first stochastic clock (4), able to produce a first clock signal (CLK1); - and a second stochastic clock (5) able to produce a second clock signal (CLK2).
