CHECKING BY PSEUDODUPLICATION |
摘要 |
An error detection system is described which detects errors by performing a given arithmetic or logical operation using one data path followed by the performing of the same arithmetic or logic operation using a different data path. The results of the two arithmetic or logical operations are then compared, the failure of the two results to be identical indicating failure of a component used in the performance of the arithmetic or logical operation.
