    • A data processing device provided with an error detection unit comprises a processor (102) arranged to support execution of an operation comprising a first sequence of instructions and execution of a second sequence of instructions implementing the operation, the first and second sequences of instructions generating, when in use, a first result and a second result, respectively. Configurable circuitry (124, 126) is also provided and arranged to support a repository (134, 136, 44, 146) to receive the first result and the second result following generation thereof. The configurable circuitry (124, 126) is configured as a function comparator unit (124) arranged to compare the first and second results for consistency and to control further execution of the first implementation and the second implementation in response to a result of the comparison.
    • 设置有错误检测单元的数据处理装置包括处理器(102),其被配置为支持执行包括第一指令序列和执行实施该操作的第二指令序列的操作,第一和第二指令序列生成, 在使用时分别是第一个结果和第二个结果。 可配置电路(124,126)也被提供和布置成支持存储库(134,134,44,146),以在生成之后接收第一结果和第二结果。 可配置电路(124,126)被配置为功能比较器单元(124),其被布置为响应于比较的结果来比较第一和第二结果的一致性并且控制第一实现和第二实现的进一步执行。
