Abstract
A multiple common memory system is provided in which at least three CPUs share at least two common memories each storing one and the same content. Each of the first and second CPUs contains a respective one of the two common memories, and each of the first and second CPUs has an arrangement to access the common memory therein at the time of requesting a read access to a common memory. Other CPUs in the system do not contain common memories, but do include arrangements to access the common memory of the first or second CPU at the time of requesting a read access to a common memory.
