| 摘要 |
The invention concerns a method for bit error injection into an equipment operating under the control of a given main programme, which consists in carrying out an interruption and introducing the bit error during the development of the interruption programme, wherein, when the error has to be injected into a target memory word stored at a site not directly accessible, the interruption programme comprises the following steps which consists in: placing in the stack (303) the content of a register (ACC), transferring (304) into the register (ACC) the content of the memory word, modifying (305) in the register (ACC) the repeated content of the target memory word to inject therein the selected error, transferring (306) the modified target memory word to its original site, unstacking (307) the register (ACC), and ending (308, 309) the interruption programme and returning to the main programme address indicated by the programme counter (PC).
