Abstract
Two or more processors with differing address space sizes are used in a multi-processor system. A portion of the memory means accessible by the first processor with a larger address space size is also accessible by the second processor for elevating a utilization efficiency of the memory capacity. A window for the memory space of the second processor is provided in the address space of the first processor. The memory devices controlled by the second processor are controlled through this window by the first processor as well for elevating the utilization efficiency of the memory devices.
