摘要: 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.

摘要: A method and system of exchanging information between processors. At least some of the illustrative embodiments may be a method comprising exchanging information between a plurality of processors by writing (by a first processor) a first datum to a logic device and then continuing processing of a user program by the first processor, writing (by a second processor) a second datum to the logic device and then continuing processing of a user program by the second processor, and writing (by the logic device) the first and second datum to each of the first and second processors after all the processors have written their respective datum to the logic device.
