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.
