Abstract
PURPOSE: To improve reliability and also to increase a degree of number of freedom for system operation by multiplied auxiliary memory units and a global memory unit which controls the whole system.
CONSTITUTION: Address widths of auxiliary memory units are denoted by (α), (β) and (γ). Processor 1 can attain access to access address (α+β) at its maximum. Processor 3 also has the maximum allowable address (α+β). Namely, although nothing seems available after (α+β), region (β) is exclusively used by processor 1 when processor 3 makes access to an address greater than (α), so that access to region (γ) will be attained by adding (β) to the access address without fail. Then, respective processes are executed actually while memories are used in common apparently. Processors can therefore be operated independently while the multiplication is stopped.
