ABSTRACT:
In an implementation of latent error detection, memory regions that each correspond to a different processor element of a redundant processor system are scanned for latent processing errors maintained as erroneous data. The data maintained in the memory regions is compared to detect a latent processing error in a first memory region. The latent processing error is resolved by copying data from a second memory region into the first memory region where the data maintained in the second memory region is determined to be identical to data maintained in at least a third memory region.
