Abstract
A highly reliable data processing system using the pair-spare architecture obviates the need for separate memory arrays for each processor. A single memory is shared between each pair of processors wherein a linear block code error detection scheme is implemented with each shared memory, wherein the effect of random memory faults is sufficiently detected such that the inherent fault tolerance of a pair-spare architecture is not compromised.
