Abstract: A method for automatically generating a sequence of Nmax instructions in assembly language, the sequence being executable error-free by a multi-core processor, the method comprising steps of: initializing registers of the processor, then selecting a first instruction of the predetermined sequence, optionally at random; and selecting an N+1th instruction among an instruction to read from a memory connected to the cores of the processor by a memory bus, an instruction to write to said memory, and a local instruction using only the registers of the processors, according to rules and to priorities between the rules, the rules using respective differences between statistical-metric values of statistical metrics of a memory access pattern of the sequence of N previous instructions having statistical-metric values, and setpoint values.
