| 摘要 |
The invention relates to a computer which comprises a first computational unit (1) and a second computational unit (2). First information comprising a first command and/or a first amount of data is processed in the first computational unit (1) while second information comprising a second command and/or a second amount of data is processed in the second computational unit (2). The first command is identical to the second command and the second amount of data consists of compensation data. The computer also comprises a coupling device (5) which is used to receive the first information and to supply second information to the second computational unit (2). The coupling device (5) is configured in such a way that the second information can be produced independently from the first information and that the second information is different from the first information. The coupling device is also embodied in such a way that the compensation data can be produced from the first information and the second command so that a checksum of logically high states of the first and second amount of data has a constant, pre-determined value. |
